Question

8) What is the slope and y-intercept of this line?

y=-3x + 9
slope: 3, y-intercept: -9
slope: -3, y-intercept: 9
slope: 1, y-intercept: -3
slope: 9, y-intercept: -3

Answer 1

Slope:3,y-intercept:-9

Answer 2

slope = - 3, y- intercept = 9

Explanation:

The equation of a line in slope- intercept form is

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

y = - 3x + 9 ← is in slope- intercept form

with slope m = - 3 and y- intercept c = 9
