The answer is Graph A.
The equation is written in slope-intercept form y=mx+b, so the slope m is 3/4, and the y-intercept is -3.
You can immediately eliminate graph B because its y-intercept is 3, not -3.
Then, you can count the rise/run for the other two graphs to see which one has a rise/run of 3/4. That’s graph A (graph C has a rise/run of 3/2, so it’s wrong).
