Meg is 6 years older than Victor. Meg's age is 2 years less than five times Victor's age. The equations below model the relationship between Meg's age (m) and Victor's age (v):
m = v + 6
m = 5v – 2
Which is a possible correct method to find Meg's and Victor's ages? (5 points)
Solve m + 6 = 5m – 2 to find the value of m.
Write the points where the graphs of the equations intersect the x axis.
Solve v + 6 = 5v – 2 to find the value of v.
Write the points where the graphs of the equations intersect the y axis.

The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below:
Car A
y = 60x + 10
Car B
y = 40x + 70
After how many hours will the two cars be at the same distance from their starting point and what will that distance be? (5 points)
2 hours, 150 miles
2 hours, 190 miles
3 hours, 150 miles
3 hours, 190 miles
