Answer:
(0, <u>3</u>), (2, <u>-1</u>), (-6, <u>15</u>)
Step-by-step explanation:
I recommend you use desmos scientific calculator for these problems.
So first you'll wan't to plug in the expression:
y=-2x+3
Then you''l want to put x= then the domains.
x=0, 2 or -6. (it doesn't matter as long as you put them in one at a time.)
youll then get each answer as you plug the numbers in.
x=0 y=3
x=2 y=-1
x=-6 y=15
Sorry if it wasn't clear to understand I'm doing my work at the same time as helping others.
Can't tell with graph but if the width is 15 more than likely the length is 13 but that is if you use the basic subtraction.
