Answer :

Given equations are 3x + 4y – 12 = 0 and 6x + 8y – 48 = 0

Let us plot the given equations. For this we will need some points to plot for the equation.

3 x + 4 y - 12 = 0

4 y = 12 - 3 x

Now let us take random values of x and obtain the corresponding values of y by putting in the equation.

at x = 0, 

4 y = 12 - 3 x 0
4 y = 12
y = 3

Now at y = 0,

3 x + 4 x 0 = 12
3 x = 12
x = 4



So we have two points for the equation 3 x + 4 y - 12 = 0 and those are (0, 3) and (4, 0)


6 x + 8 y - 48 = 0

Now let us find points for this equation

at x = 0,

6 x 0 + 8 y = 48
8 y = 48
y = 6

at y = 0,

6 x + 8 x 0 = 48
6 x = 48
x = 8

So we have two points for the equation 6 x + 8 y - 48 = 0 and those are (8, 0) and (0, 6)


3x + 4y – 12 = 0 passes through (4, 0) and (0, 3)

6x + 8y – 48 = 0 passes through (8, 0) and (0, 6)
