Question

Someone please. i need help w this,

Answer 1

y =
`(-8)/(3)` x +
`(8)/(3)`

Explanation:

The slope is the change in y over the change in x.

`(0-8)/(1 - -2)` =
`(-8)/(1+2)` =
`(-8)/(3)`

The slope (m) is
`(-8)/(3)`

Use the slope and one of the points to find the y intercept

I will use the point (1,0)

x = 1

y = 0

m =
`(-8)/(3)`

y = mx + b Substitute in what you know and solve for b

0 =
`(-8)/(3)`(1) + b

0 =
`(-8)/(3)` + b Add
`(8)/(3)` to both sides

`(8)/(3)` = b

The y-intercept (b) is
`(8)/(3)`

y = mx + b

y =
`(-8)/(3)` x +
`(8)/(3)`
