How do you change the equation 10q−5r=30 so that r is the independent variable?

r=2q-6

Step-by-step explanation:

10q-5r=30

Subtract 10q from both sides:

-5r=30-10q

Divide both sides by -5:

r=2q-6

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

you have to put the graph on here with the question
