Lesson 3.1: Linear Functions

Question 4 • (OC27) MATH COLL ALGEBRA-1200710-S1-Degele-VOL7006P

What is the slope of the equation y – 3 = –4(x – 5)?

Answer
A
–4
B
–3
C
20
D
23

Explanation

The equation is in point-slope form, y − y₁ = m(x − x₁), where m is the slope. Comparing y − 3 = −4(x − 5) with that form shows that the coefficient of the parentheses is −4. Therefore, the slope is −4, choice A.
