Well, first you would need to get y on it's own, as it is in y=mx+b.

How we would do this is dividing by 5.

-3x+5y/5=20/5

We now have -3x+y=4, so we would need y on its own side.

We would do THIS by adding 3x to both sides.

We would end with y=3x+4

We know in the equation y=mx+b, m=slope.

So in the equation y=3x+4, the slope is 3.

Please, please give brainliest, it would be greatly appreciated, I only a few more before I advance, thanks!

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
