The biggest part of this problem is understanding what the equation is for Slope-Intercept Form. The equation is y=mx+b. This looks complicated, but don't worry; it's actually quite "b" stands for the y-intercept, and "m" stands for the slope. Adriana's problem says that the y-intercept is 4, and to find Henry's answer, you need to change the y-intercept by - 1. What is 4-1? 3. If the slope, 2, stays the same, then y=2x+3! There's your answer.
