y = -2x - 3
-- The y-intercept is the point where the graph crosses
the y-axis. But x=0 everywhere on the y-axis, so
y = -2(0) - 3
y = - 3 .
-- The x-intercept is the point where the graph crosses
the x-axis. But y=0 everywhere on the x-axis, so
0 = -2x - 3
Add 2x to each side: 2x = -3
Divide each side by 2: x = -3/2 .
