1. ## help please and thankyou!

how do I write the eq'n of the lines passing through the following two points?

(3,8) and (-4,7)

2. ## Re: help please and thankyou!

use the slope formula to find the slope between the two points, then use the point-slope form of a linear equation.

3. ## Re: help please and thankyou!

what is the point-slope form?

I know how to find the slope (m= y2-y1/x2-x1)

$y - y_1 = m(x - x_1)$
