Question

Help meee pleasee!!!




thank you <3

Answer 1

y = -800x + 294000

286,000

Explanation:

To write the equation, you need the slope and the y-intercept.

The slope is -800

You find the slope by the change in y over the change in x

`(288400 - 294000)/(7 - 0)` =
`(15600)/(7)` = -800

Now we will find the y -intercept. I will use the slope and the point (0, 294,000) to find this. I could have used the other point given. They will both work.

slope (m) = -800

x = 0

y = 294000

y = mx + b

294000 = -800(0) = b

294000 = b

The equation is

y = mx + b

y = -800x + 294000

2014

y = -800x + 294000

y = -800(10) + 294000

y =-8000 + 294000

y = 286,000
