Point-Slope Form of a Line

Question 7 • AZ-Algebra 1A (MA101)

Which equation represents a line that passes through (–9, –3) and has a slope of –6?

Answer
A
y – 9 = –6(x – 3)
B
y + 9 = –6(x + 3)
C
y – 3 = –6(x – 9)
D
y + 3 = –6(x + 9)

Explanation

Use point-slope form, y − y₁ = m(x − x₁). Substituting the slope −6 and the point (−9, −3) gives y − (−3) = −6[x − (−9)], or y + 3 = −6(x + 9). This is choice D.
