Kelsey graphed the equation y = 3x + 1 as shown below.

On a coordinate plane, a line goes through points (negative 3, 0) and (0, 3).

Which describes Kelsey’s error?
Kelsey graphed the y-intercept on the x-axis.
Kelsey graphed –3 instead of 3 as the y-intercept.
Kelsey graphed the slope as up 1 right 1 instead of up 1 left 1.
Kelsey graphed the slope as the y-intercept and the y-intercept as the slope.

Answer: Kelsey graphed the slope as the y-intercept and the y-intercept as the slope.

Reason: The line through (−3,0) and (0,3) has slope (3−0)/(0−(−3)) = 1 and y-intercept 3. The equation y = 3x + 1 has slope 3 and y-intercept 1, so Kelsey swapped them.
