The cost of 4 dance lessons is $49. The cost of 12 lessons is $117. Write a linear equation to find the total cost C for x lessons.

Answer:

answer below, I think this is what you mean but idk

Step-by-step explanation:

Write out the 2 points.

(7,82)

(11,122)

2) Find the slope (change in y divided by change in x).

Slope = (122-82) / (11-7) = 40/4 = 10

3) Pick one of the points and insert it into point slope form.

y - 82 = 10(x-7)

y-82 = 10x-70

y = 10x + 12

4) Check your answer on the other point.

82 = 10(7) + 12

82=82
