Answer:
1) Y intercept: 0, 18
x intercept: (-6, 0)
2) Y intercept (0, -8)
x intercept (-4, 0)
Step-by-step explanation:
y=3x+18
y intercept is when x=0
y=3(0)+18
y=18
So y intercept is 18, 0
X intercept is when y=0
0=3x+18
-18=3x
x=-6
So the x intercept is (-6, 0)
HELPFUL HINT: the equations are already in y=mx+b form, so b is the y intercept!
y=-2x-8
Y intercept (0, -8)
x intercept
0=-2x-8
8=-2x
-4=x
x=(-4, 0)
