Line m has the equation y= 2/3 (x) - 3 . Line n has the points given in the table to the right. Holly says the two lines have the same slope. Is Holly correct?

A. Yes, they both have a slope of .
B. Yes, they both have a slope of -3.
C. No, the slope of line m is and the slope of line n is .
D. No, the slope of line m is -3 and the slope of line n is .

 A) Yes, they both have a slope of 2/3

Explanation:

The equation y = (2/3)x - 3 has slope 2/3 since it is the coefficient of x

The coefficient is the number to the left of the variable.

Now let's pull two points from the table.

Pick any two points you want. I'll pick the last two rows to get the two points (4,2) and (13,8)

Subtract the y values to get 8-2 = 6

Subtract the x values in the same order:  13-4 = 9

Divide the differences:

slope = rise/run

slope = (change in y)/(change in x)

slope = 6/9

slope = 2/3

We get the same slope as before. Holly is correct.

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 %
