Answer:

0.9%

Step-by-step explanation:

We have been given that Rich measured the height of a desk to be 80.7 cm. The actual height of the desk is 80 cm.

We will use percentage error formula to solve our given problem.

\text{Percentage error}=\frac{\text{Experimental value-Actual value }}{\text{Actual actual}}\times 100

\text{Percentage error}=\frac{80.7-80}{80}\times 100

\text{Percentage error}=\frac{0.7}{80}\times 100

\text{Percentage error}=0.00875\times 100

\text{Percentage error}=0.875\approx 0.9

Therefore, Rich's percent error in calculation is 0.9%.

Answer:

-2

Step-by-step explanation:

The slope of a line tells us how y responds to a change in x.  If the slope is 2, it means that for every time x increases by 1, will will go up by 2.

We can calculate slope from a line, or with two given points.  I used points (0,4) and (3,-2).  Slope is the "Rise/Run."

The Rise:  (-2 - 4) = -6

The Run:  (3 - 0) = 3

Slope = Rise/Run = (-6/3) = -2
