Given the equation y = 2x - 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

The slope is 2 and the y-intercept is -8

The standard equation of a line is expressed as y = mx + b

where:

Given the equation y = 2x - 8

Compared with the given equation

mx = 2x

m = 2

Hence the slope is 2

Similarly,

b = -8

Hence the slope is 2 and the y-intercept is -8

m = 2 and b = - 8

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 b = - 8
