Answer:


y = 2x - 2

Explanation:

Starting from the y-intercept of [0, −2], you do
(rise)/(run)by either moving two blocks south over one block west or two blocks north over one block east [west and south are negatives].

I am joyous to assist you anytime.

Answer:

y=2x-2

Explanation:

Slope intercept form = y=mx+b

Where m=slope and b= y intercept

Reminder: the y intercept is where x=0

Looking at the graph, the y intercept is given as (0,-2)

There are also two points given (0, -2) and (2,2)

Reminder: to find the slope, divide the changes in y by the changes in x or substitute the numbers into this equation: y2-y1/x2-x1

2-(-2)/2-0=4/2

m=2

Now that we have the slope and y intercept, sbstitute into the equation y=mx+b:

y=2x-2
