Write an equation for line AB.

Question

Refer to point A(3,5), B(4,-1), and C(9,3). Lines AB and AC meet at point A

Answer 1

(3,5), (4,-1) have line through them with slope = (5+1)/(3-4) = -6

AB line's equation is y-5 = -6(x-3) in point slope form

or

y = -6x +23 in slope intercept form

or

6x +y = 23 in standard form
