A bridge in the shape of an arch connects two cities separated by a river. The two ends of the bridge are located at (–7, –13) a

Zepler [3.9K]

We can use the formula for a parabola: $y = c(x - a) + b$ where
$(a,b)$ is the origin of the parabola and $c$ is some constant scaling factor.

We are given that the center of the arch on the bridge is $(0, 0)$ . This is our origin. So our equation is:

$y = c(x - 0)^2 + 0 = cx^2$

Now we just need to find c. We can do this by plugging in one of the other points given:

$-13 = c*7^2$
$\frac{-13}{49} = c$

So our final equation for the arch of the bridge is:

$y = \frac{-13}{49}x^2$
