The equation for the line we want to get is:
y = -x + 3
How to get the equation of a line?
A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
Two lines are perpendicular of the product between the slopes of the two lines is -1.
Here we want to find a line perpendicular to the one that passes through the line with Y(1,3) and Z(-3,-1), the slope of that line is:
a = (-1 - 3)/(-3 - 1) = 1
Then the slope of a perpendicular line, a', is:
a'*1 = -1
a' = -1
Then our line is like:
y = -1*x + b
To find the value of b, we use the fact that this line passes through (1, -4), then we will get:
-4 = -1*1 + b
-4 + 1 = b
-3 = b
So the linear equation is:
y = -x + 3

Wesley is going backpacking in a couple of days and is buying trail mix for the trip. The amount of trail mix he will bring depends on how long he plans to backpack. a = the amount of trail mix Wesley will bring /= the length of the backpacking trip Which of the variables is independent and which is dependent?
Answer: In this scenario, the length of the backpacking trip is the independent variable and the amount of trail mix Wesley will bring is the dependent variable.
The independent variable is the variable that is being changed or controlled in an experiment or study. In this case, the length of the backpacking trip is the independent variable because it is being determined by Wesley and is not influenced by any other factor.
The dependent variable is the variable that is being measured or observed in an experiment or study. In this case, the amount of trail mix Wesley will bring is the dependent variable because it depends on the length of the backpacking trip. Wesley's decision on how much trail mix to bring will be influenced by how long he plans to go backpacking.

In right triangle ABC, m∠C=3y-10, m∠B=y+40, and m∠A=90 What is the measure of ∠C?
The unknown angle of the right angle triangle is as follows:
∠C = 35°How to find the angle of a right angle triangle?A right angle triangle is a triangle that has one of its angles as 90 degrees. The sides of a right angle triangle can be named base on the position of the angles. The sides includes hypotenuse side, opposite side and adjacent side.
The sum of angles in a right angle triangle is 180 degrees. Therefore, let's find the ∠C in the triangle ABC.
Therefore,
180 = ∠A + ∠B + ∠C
m ∠B = y + 40
m ∠C = 3y - 10
m ∠A = 90°
Hence,
180 = 3y - 10 + y + 40 + 90
180 = 4y + 120
180 - 120 = 4y
y = 60 / 4
y = 15
Hence,
m ∠C = 3(15) - 10
m ∠C = 45 - 10

what is the slope of the line?
The slope of the given line is 40 mi/h.
How to find slope of the line in the graph?
The slope of a line is the ratio of rise to run. Hence, here are the steps to find slope from a graph.
Select any two random points on the graph of the line (preferably with integer coordinates).
Label them as A and B (in any order).
Calculate the "rise" from A to B. While going vertically from A to B, if we have to go
"up", then the rise is positive;
"down", then the rise is negative.
Calculate the "run" from A to B. While going horizontally from A to B, if we have to go
"right", then the run is positive;
"left", then the run is negative.
Now, use the formula: slope = rise/run.
According to the given question:
To calculate the slope of the line in given graph let point A be (5, 200) and point B (10, 400).
Run = 5
Rise = 200

The probability that the card has a multiple of 3 is 5/16. We use the concept of probability and multiples to get the answer.
Define Probability.Probability of an event = (no of possible ways it can happen) / (total number of outcomes)
Define Multiples.For instance, 20 is a multiple of 4 and 5 if we declare that 4 + 5 = 20. The remaining multiples of four can be written as follows: 4, 8, 12, and so on. Four times one equals four. Numerous other mathematical ideas can be explored with the aid of multiples knowledge.
Given, total number of the cards in the bag is from 1 to 16.
So, total number of cards = 16.
Multiples of 3 below 16 = 3,6,9,12,15.

has a cat or a dog?
The probability that a student is chosen randomly from the class has a cat or a dog is 26/29.
What is the probability?It is based on the probabilities that something could happen. The theory of probability primarily relies on the justification for probability. A coin is tossed, for instance, and the theoretical likelihood of randomly receiving a head is 1 in 2.
explanation:
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
The total strength of the class is 29
The probability that a student is chosen randomly from the class has a cat or a dog = Number of favorable outcomes / total number of outcomes
P(E) = 26/29
