$\bf slope = {{ m}}= \cfrac{rise}{run} \implies

\implies \cfrac{f(b)-f(a)}{b-a}\implies \cfrac{3.5-15.8}{2012-1970}\implies -\cfrac{12.3}{42}

CORRECT ANSWER GETS BRAINLIESTTTT!!!!!

Senior tickets (x)

Child tickets (y)

First day: 3x + 5y = 70

second day: 12x + 12y = 216

Solve the system of equations (use elimination)

Multiply first equation by -4 -4(3x + 5y = 70), which makes it

-12x - 20y = -280

(+)12x + 12y = 216 add to second equation

-8y = -64

divide by -8. y = 8

Plugin the y value to either equation ( I will choose first equation)

3x + 5(8) =70

3x+ 40 = 70

3x = 30

x = 10

Senior tickets are $10, child tickets are $8
