Question

Adriana writes the equation y = 2x + 4 to represent a line on a graph. Henry writes an equation that has a y-intercept that is 1 unit lower on the graph but has the same slope as Adriana’s line. Which is Henry’s equation?

Answer 1

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.
