Answer:
$78.25
Step-by-step explanation:
Each adult = $11.50
Each child = $8.75
3 adults and 5 children
(11.50 x 3) + (8.75 x 5)
34.5 + 43.75 = $78.25
11.50 x 3 = 34.50
8.75 x 5 = 43.75
34.50 + 43.75 = 78.23
$78.23

Answer:
First find the slope of the straight line, m=(Y2-Y1)/(X2-X1)=(17–7)/(-5–0)=-2.
Using the standard equation of a straight line, y=mx+b, we know that m=-2.
Thus, so far we know that y=-2x+b.
Now plug in the coordinates of either of the above points, that we know do lie on the straight line, into our equation, y=-2x+b, and solve for b.
I will use the first point, (0,7), to get 7=(-2)(0)+b.
Solving for b, we see that b=7.
Therefore, the equation of the straight line is y=-2x+7.
It is a good idea to check your answer on a graphing calculator.
