Answer:

[tex]The \: slope \: is \: \frac{7}{3} .[/tex]

Step-by-step explanation:

To find the slope, we have to turn the equation into the slope-intercept form which is:

[tex]y = mx + b[/tex]

The slope is the m in that form.

we will solve for y.

[tex]7x - 3y = 21 \\ \frac{- 7x \: \: \: \: \: \: = - 7x}{ - 3y = - 7x + 21} \\ \\ \frac{ - 3y}{ - 3} = \frac{ - 7x + 21}{ - 3} \\ y = \frac{7}{3} x - 7[/tex]

Answer:

Step-by-step explanation:

-3y = -7x + 21

3y = 7x - 21

y = 7/3x - 7

slope is 7/3

answer is C
