Answer is : y=-3x+1

put coordinates and slope into slope equation (y=mx+b) so it would be 7=-3(-2)+b and then solve for b. when you have b (which is 1) plug it into slope equation which would be y=-3x+1

Rhonda can travel 45 miles in 3 hours while on her skateboard. at this rate, how many hours does it take to travel 1 mile

Rasek [7]

The question is relating Rhonda's distance travelled and time taken

If 45 miles = 3 hours

Then, 1 mile = 3/45 hours

$=\frac{1}{15}$

Therefore, it will take Rhonda 1/15 hours to travel 1 mile.
