Question

18. What is the equation for the relation? HELPPPPP​

Answer 1

C. 1/2N +400

Explanation:

So the 400 is reqiured in the equation as

x =0 , y= 400.

To find the slope you can do rise over run:

`(y_2-y_1)/(x_2-x_1)` =

`(500-400)/(200-0) =(100)/(200) =(1)/(2)`

Answer 2

The line crosses the vertical axis at 400, so the equation has to be "C = something + 400".

If you pick any point and go up 100 and over 200, you get back on the line, so the slope is 100/200 or 1/2

Option C: C = 1/2 N + 400
