Question

Given the equation y=2 x-8, what is the slope and the y-intercept

M= 2 and b=8
M=2 and b= -8
M=8 and b =2
M= -8 and b= 2

Please help I really don’t understand;(

Answer 1

m = 2 and b = - 8

Explanation:

The equation of a line in slope- intercept form is

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

y = 2x - 8 is in this form

with slope m = 2 and y- intercept b = - 8
