Answer:
y=-5/2x-19/2
Step-by-step explanation:
The vertex of the quadratic equation is (-7,8).
Isolate the variable y for the equation 2x-5y=7
You get y = 2/5x-7/5
The slope we have to find is the inverse of the current slope.
So the slope for the final equation is -5/2.
Then use point slope form to get y - 8 = -5/2 * (x+7)
Then convert it into slope intercept form to get y - 8 = -5/2x - 35/2
Then add 8 to each side to get y=-5/2x-19/2
