You have the intercepts and x-coordinate of the vertex correct. There appears to be a math error in the calculation of the y-value of the vertex.
f(7/8) = (4*7/8 -7)*(7/8) -15 = -49/16 -15 = -289/16 = -18.0625
Answer:For this problem, you will need to use the pythagorean theorem which is
So a and b are usually the sides that are NOT the hypotenuse, or in this case the long side that is not at a 90 degree angle.
You will start by plugging 12 into with (a) or (b) but not both. And then you will plug 17 in for (c). Make sure you square these values to solve the equation. Once you do that, it is basic algebra from there to solve for the missing variable. If you want to check to see if your answer is correct, then plug all the side numbers back into the equation. Also your answer should be between 12 and 17, or possibly one of those numbers.

Answer:
x-intercept: 15
y-intercept: -6
The slope is positive because 2/5 (the slope) is positive.
Step-by-step explanation:
The x-intercept is where the line crosses the x-axis.
The y-intercept is where the line crosses the y-axis.
541-(64x)=-803
1344=64x
x=21
I am pretty sure the rate would change faster if it went by -2's. This would create a steeper slope than the slope 1/2 created. So again, i think it would be a greater rate of change if it changed by negative twos.
I hope this helped :P
