Question

A line has a slope of 2 and a y-intercept of(0, -4). What is the value of y when x = 6?

Answer 1

the slope intercept form of a line is

y = mx + b

m = slope and b = y-intercept

so in your line you have m = 2 and b = -4

so the line is

y = 2x - 4

now just substitute x = 6 to find y

Answer 2

Thanks!

y=8?

Answer 3

yes
