Question

What is the equation of the line that contains the points with (x,y) coordinates (-3, 7) and (5, -1)?

a. y=3x-2 b. y=x+10 c. y=-x +4
d. y= - (1/3)x +8 e. y= -(3/2)x + (11/4)

Answer 1

slope=(7+1)/(-3-5)
=8/-8=-1
(y+1)/(x-5)=-1
y+1=5-x
x+y=4
y=-x+4

Answer 2

here we take any point(x,y) on line.
