Graph the line.
y=3x-7

Graph The Line.y=3x-7

Answers

Answer 1

Step-by-step explanation:

so the -7 means that the line will cross the y-axis at the point (0,-7). from there, we knows the slope is 3. slope is rise over run, so 3 over 1. we go up 3 and over 1

Answer:

y=(-3/4)+2

Step-by-step explanation:

Hello there! In order to solve this problem we will have to find the slope of the line and then use the point slope formula

Firstly, lets solve for the slope by finding the change in y over the change in x:

slope (m)= [tex]\frac{y2-y1}{x2-x1}[/tex]

We will plug in the values of the points given and find that:

slope (m)= [tex]\frac{-1-2}{4-0}[/tex]

this equals (-3/4)

from here we will use the point slope formula to find for the equation that the line passes through. You can use either point for this step, I will be using A(0,2).

Point-slope equation:

[tex]y-y1=m(x-x1)[/tex]

Plugging in values:

[tex]y-2=(\frac{-3}{4})(x-0)[/tex]

after isolating y we find that the equation is:

[tex]y=\frac{-3}{4} x+2[/tex]

Hope this helps!

Subtract: 3.8 - 2.923. Explain in your own words how you would solve this, in detail, from start to finish.

Answers

Given:

3.8 - 2.923

To find:

The subtraction.

Solution:

We have,

3.8 - 2.923

It can be written as

3.800 - 2.923

After subtraction, we get

3 . 8 0 0

-2 . 9 2 3

------------------

0 . 8 7 7

-----------------

So, 3.800 - 2.923 = 0.877.

Therefore, the value of 3.800 - 2.923 is 0.877.

The equation y = 3x + 1.25 represents the cost, y, in dollars, of bowling x games and renting a pair of bowling shoes. Shoes are rented for a flat rate that does not depend upon the number of games bowled. What does the slope of this equation represent? *

Answers

Answer:

Cost per game

Step-by-step explanation:

Given

[tex]y = 3x + 1.25[/tex]

Required

What does the slope represent?

First, we need to determine the slope

A general equation is of the form

[tex]y = mx + b[/tex]

Where

[tex]Slope = m[/tex]

By comparing:

[tex]y = mx + b[/tex] to [tex]y = 3x + 1.25[/tex]

[tex]m = 3[/tex]

Hence, the slope is 3

From the question we understands that a certain amount is paid per games.

This amount is represented by the rate or slope.

So:

The slope is the cost per game

I’m not sure but m 5 is 97 and m 8 is 83

Answer:

Angle 8 = 83

Angle 5 = 180 -83 = 97

Step-by-step explanation:

Check: Just an example to check using Co- interior angles

Angle 2 + Angle 5 =  180 degrees

                83 +97  = 180 degrees

       180 degrees = 180 degrees

Therefore Angle 5 = 97 degrees and Angle 8 = 83 degrees
