for example, in the first equation.

4x + 3y = 12

for x-int:

4x + 3(0) = 12

=> 4x = 12

=> x = 3

so the x-intercept is (3,0) and that is one point to plot

for the y-int:

4(0) + 3y = 12

=> 3y = 12

=> y = 4

so (0,4) is the y-intercept which is another point to plot.

so you can plot those two points on graph paper and draw a straight line through them with the aid of a straight edge. do a similar thing for the other line
