Question

What are the slope and y-intercept for the line y = -1/2x + 3

A.) slope = 1/2 y-intercept = 3
B.) slope = -1/2 y-intercept = 3
C.) slope = 1/2 y-intercept = -3
D.) slope = -1/2 y-intercept = -3

(10 points)

Answer 1

the answer is B. because the formula for slope is y=mx+b and m is the slope and b is the y-intercept so if you look at your equation you are able to classify the slope as -1/2 and the y- intercept as 3

Answer 2

B

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = -
`(1)/(2)` x + 3 is in this form

with slope m = -
`(1)/(2)` and y - intercept c = 3
