Question

What are the slope and y-intercept of the graph of y = −1/3x + 1 ?

A. slope: -1/3 ; y-intercept: 1
B. slope: 1/3 ; y -intercept: -1
C. slope: 1 ; y-intercept; -1/3
D. slope: 1/3 ; y-intercept: 1

Answer 1

Slope is the number or fraction that is mutiplying the x, and the y-intercept is the other number.

The answer should be A

Answer 2

A. slope = -1/3; y-intercept = 1

Explanation:

The equation for a straight line is y = mx + b, where m is the slope and b is the y-intercept.

Your equation is y = -1/3x +1.

If we compare like terms, we see that the slope m = -1/3.

The y-intercept is the value of y when x = 0.

y = -1/3(0) +1

y = 1
