A line goes throught the points (0,-9) and (-9,-72)<br><br>what is the slope of the line?

Vladimir [108]

To find the slope(m) of the line, you use the slope formula:

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

And you plug in the points into the equation.

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m = \frac{-72-(-9)}{-9-0}$

$m = \frac{-72+9}{-9-0}$

$m = \frac{-63}{-9}$

m = 7

74$ for working 6 hours.what is the hourly pay rate in hours per dollar

fgiga [73]

Answer:

.081 hours per dollar

$12.333 dollars per hour

Step-by-step explanation:

I'm a bit confused whether you just want hours per dollar or also dollars per hour, so I'll answer both.

First, for the dollars per hour, you want to do 74 divided by 6 equals 12 1/3. So each hour you get paid $12.333

Fort the hours per dollar, you do 6 divided by 74 equals .081.
