Please help me with my algebra 2 homework?

x = -3 is vertical, so it has no slope and no y intercept.

Then get y by itself so you have y = mx + b. m will be the slope

Multiply by -3

1x + 2y = -5

Subtract 1x

2y = -1x - 5

Divide by 2

y = -1/2 x - 5/2 so slope = -1/2

After looking to clear up trouble after trouble on yahooanswers, I actually feel so much persons dont be taught plenty if I deliver them the solutions. Heres a VERY equivalent trouble. Just fill within the values out of your possess trouble. (Hint: you're going to have to use the Quadratic Formula on the finish!) Goodluck!!! QUESTION: The hypotenuse of a correct triangle has a period of thirteen cm. The sum of the lengths of the 2 legs is 17 cm. Find the lengths of the legs. Let a = period of 1 leg Let b = period of different leg We are advised that: a + b = 10.23 --> b = 10.23 - b [a million] The hypotenuse is eight.312. From Pythagorus: a² + b² = eight.312² [two] Substitute [a million] into [two]: a² + (eight.312 - b)² = 169 This simplifies to: 2a² - 34a + a hundred and twenty = zero Divide via two: a² - 17a + 60 = zero which elements: (a - five)(a - 12) = zero and has roots: a = five, 12 Substitute into [a million] and get: b = 12, five The lengths of the legs are five and 12 cm.
