Answer:
y - 12 = 9(x - 4)
Step-by-step explanation:
The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph. Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into y - k = a(x - h)^2, obtaining
21 - 12 = a(5 - 4), or 9 = a. With a known, we can write the desired equation:
y - 12 = 9(x - 4)
X +(-5y)= 13
-x+ 9y =(-17)
0+<u>4y</u>=<u>-4</u>
4 4
y=1
x+-5(1)=13
x-5=13
+5 <u>+5
</u> x=18
y=1
