Writing a linear equation
quick
check
use the work shown below to write the equation for a line wha
that passes through the points (-5,0) and (-1, -8).
1. use slope formula to find slope:
o!
-8-0 -8
m=-1 - (-5) = 45
8 = -2
.
what is the answer

Step-by-step explanation:

First find the slope of the line that passes through the points (-5,0) and (-1, -8).  Notice how x increases 4 units from -5 to -1 and y decreases 8 units.

Thus, the slope of this line is m = rise / run = -8/4, or m = -2.

Another way to look at this:

       change in y      - 8 - 0

m = = = -2

        change in x       -1 - (-5)

Please note:   m=-1 - (-5) = 45

8 = -2 is not correct; 8 cannot equal -2.

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
