If (y=7x+b) and (y=-5x+9) cut the (y)-axis at the same point, what is (b)?

Answer and explanation

Correct answer: 9

To find a line’s y-intercept, put x=0. The y-intercept of y=7x+b is b, while that of y=-5x+9 is 9. Since both lines cut the y-axis at the same point, their y-intercepts must be equal: b=9. The value 12 may come from the difference of the slopes, but slopes do not determine the y-intercept. Exam tip: for a y-intercept question, always substitute x=0.
