Hello :
an equation is : y-5 = 0( x+7)...(the slope =0 '<span> horizontal line ' )</span> y=5
Answer:
10
Step-by-step explanation:
because 25 is 5 times as much so you multiply 5 by 2 and you get 10.
The discriminant of this equation is 49. The solutions for this equation are x=2 and x=-

I hope that helps.
