What are the intercepts of the line x-3y=9? a. intercept: ; intercept: b. intercept: ; intercept: c. intercept: ; intercept: d. intercept: , intercept:

-\frac{9-x}{3}[/tex]

Step-by-step explanation:

x-3y=9

isolate y for x

x-3y=9

subtract x both sides

x-3y=9

-x      -x

-3y=9-x

divide both sides by -3

y = -\frac{9-x}{3}[/tex]

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
