Answer:
Your answer is y=4/4x -3 or y=1/1x-3
Explanation:
First you start of with your y-intercept, which is the number where the dot is on the y-axis
That number is -3
For the slope you have to find rise/run for this problem your rise would be 4 and your run would be 4 because you are going from one point to the other. It can also be simplified down to 1/1 as well.
Hope this helps
