Answer:

A.) -5

Step-by-step explanation:

<em>Slope Formula --->     </em>m = \frac{y_2 - y_1}{x_2 - x_1}       <em>m = slope</em>

m = \frac{2 - (-3)}{-2 - (-1)}

<em>Eliminate negatives:</em>

m = \frac{2 + 3}{ -2 + 1}

<em>Solve:</em>

m = \frac{5}{-1}

<em>Simplify:</em>

m = -5

Alice planted some corn in the back yard and measures it’s height regularly. The last time she checked, the stalks were 60 inche
sdas [7]

Answer:

The percent of increase in height of the stalks is 20%.

Step-by-step explanation:

The general formula for a percent increase is as follows:  (Original Amount - New Amount/Original Amount) x 100.  The original height of the stalks was 60 inches tall.  The new height of the stalks is 72 inches.  In the numerator of our fraction, we take 72-60 to get 12.  Our denominator is the original amount, or 60.  This gives us an overall fraction of 12/60, which when we divide gives us 0.2.  Once we multiply our decimal by 100, we get an overall percent increase of 20%.
