Question

What is the equation in point-slope form of the line passing through (4, 0) and (2, 6)?

A) y = 4x − 2
B) y = 2x − 4
C) y = −3(x − 4)
D) y = 3(x + 4)

Answer 1

1- find the slope using the 2 points

Answer 2

\[y-y _{1}=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\left( x-x _{1} \right)\]

Answer 3

2- use any point to find the equation of the line
y-y1=m(x-x1)
m: is the slope
x1 and y1 is the point
