Question

What value of x gives y=-2?

plz help !

Answer 1

-1

Explanation:

to find x, use the following formula:

y = mx + b

(y = 0)

(m = change in y-value ... which is 2)

(x = change in x-value ... which is 2)

(b = y-axis ... which is -2)

y = mx + b

y =
`(2)/(2)` + -2

`(2)/(2)` = 1

y = 1 + -2

y = -1
