Question

What is an equation of the line that passes through the points (8, -8) and (1,6)?

Put your answer in fully reduced form.

Answer 1

Explanation:

P1 = ( 8 , -8 ) = ( X1, Y1 )

P2 = (1,6 ) = (X2, Y2 )

slope = M= (Y2-Y1) / (X2-X1)

M = (6 - (-8) ) / (1-8)

M = 6+8 / -7

M = 14 / -7

M= -2

form of slope intercept equation ⇒ y = Mx + b

plug in one of our points , either works.

-8 = -2(8) + b

-8 = -16 +b

8= b

sooo

y = -2x + 8 is the answer

y = -2X+8
