33) To graph:
3x + 4y = 12
First find the y-intercept by substituting x=0 and then solve for y
That is;
3(0) + 4y = 12
4y = 12
Divide both-side of the equation by 4
y= 3
y-intercept is (0, 3)
Similarly,
To get the x-intercept, substitute y=0 and then solve for x
3x + 4(0) = 12
3x = 12
Divide both-side by 3
x=4
The x-intercept is (4,0)
