Question

whats an equation for the line having (1,-6)and(-4,4)?

Answer 1

find the slope (4- -6)/(-4-1) = 10/-5 =-2
y=-2x+b
substitute a point in
4=-2(-4)+b
b=-4
y=-2x-4

Answer 2

(x-x1)/(x2-x1)=(y-y1)/(y2-y1)
all u have to do now is replace x1=1 x2=-4 y1=-6 and y2=4...and u'll get an eq with x and y only
