Question

State the xintercept
and yintercept
for the graph of each equation. Then, graph the
equation using the xand
yintercepts.
1. 2x + 3y = 12
2. y = 2x - 4

Answer 1

ok so to solve the x intercept we set y equal to zero.
So: 2x + 3(0) = 12
2x=12
x intercept=6
Now we do the same for y.
2(0)+3y=12
y intercept=4

Answer 2

we do the same thing for 2.
0 = 2x - 4
4= 2x
x intercept=2
y=2(0)-4
y intercept= -4
