Graph the following linear equation using one of the following methods:

Question

1st slope intercept form y = mx + b
2nd table of values
3rd x-intercept and y-intercept

1. 3x + 4y = 12

Answer 1

intercepts are easiest
when x=0, 4y=12, so y=3
when y=0, 3x=12, so, x=4

So, plot the points (0,3) and (4,0) and draw a line through them.
