Question

Which of the following has a slope of 2 and a y-intercept of –4?

y= 2x-4

y= -2x-4

y= -2x +4

y= 2x +4

Answers

first cz the equation is in the slope y intercept form

y=mx+b

m is always the slop and b the y intercept

in our case 2 is the coefficient of x,so 2 is the slope of the line while -4 is the y intercept

#1

first 2

#2

the first choice.

#3

Slope-intercept form is y = mx + b

m is the slope

b is the y-intercept

A.) y = 2x - 4

has a slope of 2 and a y-intercept of -4
