Question

Find the equation, in slope-intercept form, of the line through the pair of points

(2,0) (3,4)

Answer 1

`y=4x-8`

Explanation:

Find the slope using the slope formula:
`(y_2-y_1)/(x_2-x_1)`, m=4

Use any set of points you know to solve for b. (2, 0)

Pug in everything you know: 0=4(2)+b

You get: 0=8+b

Subtract 8 to get the b by itself. b=-8.

Now just plug in and you'll get the answer!
