Question

Which of the following are equations for the line shown below? Check all that apply.

A. Y= x-2
B. Y-1=(x-3)
C. Y=x-2
D. Y+4=(x+2)

Answer 1

Answer: D.
`y+4=(x+2)`

Explanation: Once you subtract
`4` from both sides, in order to solve for y (as the equation needs to be in the slope-intercept form, otherwise known as
`y=mx+b`), you end up with
`y=x-2`, which is the right answer. It is the correct answer because the y-intecept shown in the equation matches what is on the graph, in addition to the fact that the slope is just
`x`.
