Answer:
slope = [tex]\frac{7}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 7x - 3y = 21 into this form
Subtract 7x from both sides
- 3y = - 7x + 21 ( divide all terms by - 3 )
y = [tex]\frac{7}{3}[/tex] x - 7 ← in slope- intercept form
with slope m = [tex]\frac{7}{3}[/tex]
