You can put this solution on YOUR website!
(6-(-4)*4=40 IS THE INCREASE IN THE Y VALUE BECAUSE THE LINE HAS A SLOPE OF 4 NOW ADD THE STARTING Y POINT 4 WE HAVE A NEW Y POINT OF 44
(6,4)(-4,44) HAS A SLOPE OF
(44-4)/(-4-6)
40/-10
-4
THE LINE EQUATION IS
Y=mX+b
4=-4*6+b
4=-24+b
b=4+24
b=28
b=6+24
b=30 THIS IS THE Y INTERCEPT & THE LINE EQUATION IS:
Y=-4X+28
