write the equations in the form y = mx + c where m is the gradient and c is the y intercept.
a. 5y = 9x
Y =(9/5 )x + 0 m = 9/5 ,c =0
b. 4y =12 x + 1
Y = 3x + ¼ m = 3, c=1
c. 9 – 2x = 4y
(9/4) – (½)x = y m = -1/2 c=9/4
d. 1/3 x + 1/4y - 2 = 0
( ¼)y =-(1/3)x +2 multiple the equation by 4
Y = (-4/3)x +8 m = -(4/3) c= 8
