1 y = 4 x -8
Divide by 1
y = 4 x -8
Compare this equation with y=mx+b
slope m = 4 0.8
The slope of a line parallel to the above line will be the same
The slope of the required line will be 4
m= 4 ,point ( 3 , 9 )
Find b by plugging the values of m & the point in
y=mx+b
9 = 12.00 + b
b= -3
m= 4
Plug value of the slope and b in y = mx +b
The required equation is y = 4 x -3
y = 4 x -3
