If (y=ax-12) and (y=10x+5) have equal slopes, what is (y) on the first line at (x=3)?

Answer and explanation

Correct answer: 18

In the form y = mx + c, the coefficient of x, m, is the slope. Since the two lines have equal slopes, a = 10. Substituting x = 3 in the first line gives y = 10(3) - 12 = 18. The value 20 would not account correctly for the constant term -12. Exam tip: for lines with equal slopes, compare the coefficients of x.
