Question

Write 3x+2y=18 in the form of y=mx+c find the value of m,c .does 4,3 lies on this linear equation

Answer 1

To check (4,3) lies on the line , 3x+2y = 18

LHS = 3(4) + 2(3) = 12 + 6 = 18

RHS = 18.

Hence (4,3) lies on the given line.

Given line in the form of y = mx+c is

y = (-3/2)x + 9

Where slope m = -3/2

And c = 9
