i think the last one Y = 1X
The vertex is (-3,3),so a =-3, b=3. a+b=0

Answer:
5√5
Step-by-step explanation:
Use the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-7-(-2))² +(-7-3)²) = √((-5)² +(-10)²) = √(25 +100)
d = √125 = √(25·5)
d = 5√5 . . . . distance between the points
Well it would be 63$ if we are not including tax because 80-17=63
