Answer:
Slope = [tex]\frac{7}{3}[/tex]
Step-by-step explanation:
Slope intercept form is Y= mx + b. So, you just need to get y by itself.
7x - 3y = 21
1) Subtract 7x
-7x + 7x - 3y = -7x + 21
-3y = -7x + 21
2) Divide by -3
-3y/-3 = [tex]\frac{-7}{-3} x + \frac{21}{-3}[/tex]
y = [tex]\frac{7}{3} x -7[/tex]
-7/-3 is the same as 7/3 because a negative divided or multiplied by a negative is a positive. so mine as well just put it as a positive fraction.
Slope = [tex]\frac{7}{3}[/tex]
