Question

A line has a slope of 2 and passes through the point (4, 0). What are the coordinates of another point that is on the line?

a.(2, 0)
b.(0, 2)
c.(4, 6)
d.(6, 4)

Answer 1

First you have to determine the equation of the line that has a slope of 2 and goes through the point (4, 0).

Answer 2

Do you know how to do this?

Answer 3

No >.<

Answer 4

The general linear equation is y = mx+b where m is the slope

so m = 2

which means

y = mx+b

becomes

y = 2x+b

Answer 5

We're given the point (4,0), so x = 4 and y = 0

Answer 6

Plug these two in to get

y = 2x+b

0 = 2(4)+b

0 = 8 + b

Keep going to solve for b
