Y2-y1/x2-x1= -47-(-7)/-19-(-9)= 4
The vertex of this parabola has coordinates (1,-1).
The axis symmetry goes trough the vertex. The equation of the axis of symmetry is x=1.
Answer:
slope= 0
Step-by-step explanation:
slope (m)= 0/10= 0
the line belongs to a horizontal line, so the slope is 0
equation= y=5
Andy's rental car 20+30n
Buddy's rental car 36+28n
20+30n=36+28n
2n=16
n=8
cost for 8 days is 20+30*8=260
Cost will be the same for both companies for 8 days. Cost is $260
