Tiana uses the equation c equals 21h to figure out the total amount, c, she should charge a customer for babysitting for h hours. What is the constant of proportionality? What does it mean

because they could drop even lower..

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
