Using the slope formula, find the slope of the line through the points (0,0) and (4,8).
Use pencil and paper. Explain how you can use mental math to find the slope of the line. (please show how to do on pencil and paper)
Answers
Answer:
[tex]m = 2[/tex]
Step-by-step explanation:
Using mental math to find the slope of the line:
If you think about the formula, then you set up the points in your head, you will notice that the first point is on top of the second point. And that way makes it easy to simplify. All you would need to do is subtract down in your head: For example:
(0, 0)
(4, 8)
As you can see, the first point is on top of the other, and that way you can just subtract from bottom to top. If you do it that way, it is set up (Remember, you would do this all in your head)

What is the y-intercept of the line given by the equation y = 5x + 16?
Answer here
SUBNI
Answers
Hi!
This equation is written in ' y = mx + b ' form, where m is the slope, and b is the y-intercept.
Therefore, looking at this equation, we can see that 16 is the y-intercept.
Hope this helps! Let me know if you need any other help :D
Answer:
the y intercept is (0,16)
Step-by-step explanation:
In an equation like this y= 5x+16. The number next to x would be the slope and the number after the x would be the y intercept.
Does it pass the vertical line test. Pls help..
Is this a function?
Answers
Answer:
This is a function
Step-by-step explanation:
The vertical line test is a test where you take a straight vertical line and move it from right to left. If during the test, the line touches two points at the same time, it's not a function. In this case, it is a function since it passes the vertical line test.

The slope of the one of the top is -1/4
The slope of the one on the bottom is 1/6
Step-by-step explanation:
The one on the top goes down by 1 (negative) and goes 4 to the right (positive), which can be written as -1/4, which is the slope.
The one on the bottom goes up by 1 (positive) and goes to the right by 6 (positive), which can be written as 1/6, which is is the slope.

Step-by-step explanation:
I used distance formula to calculate. But if you haven't learned distance formula or solving radical equations, or solving equations by taking sq roots then maybe you were just supposed to graph it and look for the points.

Choose the equation of the horizontal line that passes through the point (2,4).
Oy = 2
O x= 2
O y = 4
O x=4
Answers
Answer:
y = 4
Step-by-step explanation:
Refer to the two images below
For the graph:
y = 2 - red
x = 2 - blue
y = 4 - green
x = 4 - purple
Horizontal lines are parallel to the x axis. The only two equations parallel to the x axis are y = 2 and y = 4 so x = 2 and x = 4 cannot be the answer.
The point (2,4) is graphed as well as the equations and the only equation that's horizontal and passes through the point (2,4) is y = 4
Solve for y.
