\sf Solve \ for \ b. \\  \\ h =  \frac{-b}{2} a  \\  \\ Flip \ equation \\  \\  \frac{-1}{2} ab = h  \\  \\ Divide\ both \ sides\ by  \frac{(-a)}{2}  \\  \\  \frac{1}{2}ab/ \frac{-a}{2} =  h / -a / 2 \\  \\ b =  \frac{-2h}{a}

Answer:

(-4,9)

Step-by-step explanation:

To solve the system of equations, you want to be able to cancel out one of the variables. In this case, it'd be easiest to cancel out the x variables. To do this, you'll want to multiply everything in the first equation by 2 (2(x-5y=-49)=2x-10y=-98). Then, you can add the two equations together. 2x and -2x will cancel out, so you'll be left with -11y=-99. Next, solve for x by dividing both sides of the equation by -11, which will give you y=9. This is your y-coordinate! At this point, you're halfway to the answer as you just need your x-coordinate. It's not too difficult to find the x-coordinate, since you just substitute 9 into one of the equations. It doesn't matter which one you choose as you should get the same answer with both. I usually substitute the y-value into both equations, though, just to make sure I'm correct. Once you put the y-value into the equations, you should get x=-4 after solving it. :)
