Step-by-step explanation:
Answer: A) y=25, B) y=10 C) y=-5 D)y=-20
Step-by-step explanation:
So whenever you have a question like this just plug in the values.
A) x=0
y= -3x+25 will now turn into y=0+25, so y=25
B) x=5
y= -3x+25 is now y= -15 +25, so y=10
C) x=10
y= -3x+25 is now y= -30+25, so y=-5
D) x=15
y=-3x+25 is now y= -45+25, so y=-20
