On the x-axis, y = 0. We have:
0 = -3x - 4
3x = -4
x = -4/3
Thus, (-4/3, 0) is the x-intercept.
On the y-axis, x = 0. We have:
y = -3(0) - 4
y = 0 - 4
y = -4
Thus, (0, -4) is the y-intercept.
Hence, to graph the equation, we just need to draw a straight line through the points (-4/3, 0) and (0, -4).
