Answer:
Her average speed is 94 km/h
Time taken is 3.5 hours
Step-by-step explanation:
Let Evan’s average speed be x km/h.
now since Meghan drove faster, according to the question, we can say her average speed would be x + 6 km/h
Mathematically, time = distance/speed
so; since time is the same; we have
308/x = 329/(x + 6)
cross multiply
329(x) = 308(x + 6)
329x = 308x + 1848
329x-308x = 1848
21x = 1848
x = 1848/21
x = 88 km/h
Meghan average speed = x + 6 = 88 + 6 = 94 km/h
Time taken would be 329/94 = 3.5 hours

Answer:
the answer of your question is B
Slope can be calculated using the formula: m= 
y1/x1 represents the first number in the bracket
y2/x2 represents the second number in the bracket
Calculation
m =
m = 
m= 6/-12
m= -0.5 or -1/2
Therefore, the answer is B.
Replace x with -2 in the equation and solve.
3(-2) +1 = -6 + 1 = -5
