Answer:

y = 3x + 3

Step-by-step explanation:

y = mx + b where m= slope and b= y-intercept

the y-intercept is the point where x=0 or where the line crosses the y-axis.

This happens at (0,3) on the graph, so the y-intercept, or b, is equal to 3.

for m, slope can be defined as rise/run. So starting from a point you are given on the graph (-1,-2), count the number of spaces up you rise and how many you must go over (run) to get to the next point (0,3)

if you count, you should rise from (-1,-2) 5 spaces and move to the right (run) 1 space to get to (0,3).

rise/run = 3/1

3/1 = 3

the slope is 3.

now that you have the slope and the y-intercept, you can just plug it into the equation

y = 3x + 3
