Adriana writes the equation y is equal to 2 x plus 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?

In slope-intercept form, y = mx + b, the slope is m and the y-intercept is b. Adriana’s equation y = 2x + 4 has slope 2 and y-intercept 4. Henry needs the same slope and a y-intercept 1 lower, which is 3, so his equation is y = 2x + 3.
