Question

The equation shows the relationship between x and y: y = −7x + 9 What is the slope of the equation?

A. −7
B. −2
C.7
D. 9

Answer 1

A (-7)

Explanation:

compare y = −7x + 9 to the slope-intercept form of the equation of a straight line: y = mx + b.

Here -7 corresponds to the slope, m, and 9 corresponds to the y-intercept, b.

The slope of the line represented by y = −7x + 9 is thus A (-7).
