Piano lessons cost $30 per lesson. Find ordered pairs that represent the total cost for x number of lessons. Check all that apply. 0 (-1,-30) 0 (0,30) O (1,30) O (1.5,50) (3,90)

Step-by-step explanation:

y = 30x

y = 30(1)= 30 (1, 30)

y = 30(3)= 90  (3, 90)

y = 30(-1) = -30  (-1, -30)

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
