Answer:
y = -4
Step-by-step explanation:
How to find the y intercept:
y=2x-4 (Substitute "x" for zero "0")
y=2*0-4 (Solve the equation)
Answer: y = -4
How to find the x intercept:
y=2x-4 (Substitute "y" for zero "0")
0=2x-4 (Move the variable to the left)
-2x=-4 (Divide both sides)
Answer: x = 2
To graph it, go on your coordinate plane and to the x axis. Once you find the point "positive 2" or 2, go down four spaces to "negative 4" or -4. Then just draw your line and you should have your answer!!
I hope this helped!! :]

The discriminant can be found using the formula b^2-4ac
First put your equation in standard form, where all your values are on one side, and just add f(x) or y in front of your equation.
y= 8p^2-8p+2
The first value of your equation is a (a=8)
The second term of your equation is b (b=-8)
The last term of your equation is c (c=2)
Plug in the values to the discriminant equation b^2-4ac
Same as before, if we take 368 to be the 100%, how much is 20% off that?
so, the discount is that much, thus, the discounted price is then 368 - d.
