Equation in vertex form, y= (-1/4) x² + 4
<u>Step-by-step explanation:</u>
we have the equation,
y = ax² + 4 ( we need to find "a")
Now we have,
2 = a(4)2 + 4
2 = a (8)+ 4
2-4 = 8a
-2= 8a
a= -1/4
Substituting the value of "a" in the equation, we have
y = (-1/4)(x- 0)² + 4 (or) y= (-1/4) x² + 4
The parabola is opens downward. Therefore the vertex is above the x-axis and then the parabola passes through a point below the x-axis.
Equation in vertex form= y= (-1/4) x² + 4

Hello,
Slope is rise/run, or y/x, and if you are given two pairs of points, this is the equation needed: (y2-y1) over (x2-x1).
Let me plug in the numbers: (4-(-2) over 5-(-3). And that is 6/8, which then is simplified to 3/4. So the slope of those two given points is 3/4. We do not divide or simplify it into a decimal because slope is a fraction, so we leave 3/4 as it is.
Hope this helps, and that my explanation is not too confusing!

Answer:
slope = 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (- 1, 0)
m =
=
= 1
