Pls help me im so confused and i need this done!

Step-by-step explanation:

using equation y=mx+c where y is -7, x is 6 and m is 1/3

equate them in the equation to work out c

1/3 × 6 is 2

subtract 2 on both sides to find c

The equation is

based out of the following options you have:

i would expand each equation you have and equate it in y=mx+c to see where you have the same equation as above.

It looks like the third option is correct:

writing out the third option

expanding the right side my multiplying. 1/3 × x is 1/3x. 1/3 × -6 is -2

subtract 7 on both sides so you have y on its own

so the third option is the same equation as y=1/3x - 9

it would take 7/10 of an hour too fill the pool.
