x1 y1 x2 y2
3 4 8 14
slope m =(y2-y1)/(x2-x1)
(14-4)/(8-3)
(10/5)
m=2
Plug value of the slope and point (3,4) in
Y = m x + b
4.00 = 6 + b
b= 4 - 6
b= -2
So the equation will be
Y = 2 x -2
-2x+y+2=0
This cuts the X axis at A so y=0
plug y=0
-2x=-2
/-2
x=1
A(1,0)
Plug x=0 for y intercept
y=-2
B=(0,-2)
