Answer 1

x + 4y = -16 (put in slope intercept form)
4y = -x - 16
y = -1/4x - 4 ---> slope is -1/4, y intercept is -4
x intercept is found by subbing in 0 for y...x int is -16
so plot your points for this line at (0,-4) and (-16,0) then connect the points

3x + 2y = 12
2y = -3x + 12
y = -3/2x + 6 --> slope is -3/2, y intercept is 6, x intercept is 4
plot your points for this line (0,6) and (4,0)

Once these are graphed, the lines will intersect at (8,-6) -- your solution
