Answer:

143 oil changes

Step-by-step explanation:

We first find the unit rate.

(91 oil changes)/(7 days) = 13 oil changes/day

Since we want to know the number of oil changes in 11 days, we multiply the unit rate by 11 days.

13 oil changes/day * 11 days = 143 oil changes

What is the slope of the line that contains the point (-1,8) and (5,-4) answer.com?

pshichka [43]

THE SLOPE IS -2

if we have the coordinates of two points on a line, we can find the slope with this formula:
$s = \frac{y2 - y1}{x2 -x1} = \frac{y1 - y2}{x1 - x2}$
so the slope is
$\frac{8 - ( - 4)}{ - 1 - 5} = \frac{12}{ - 6} = - 2$
the answer is -2

good luck
