Slope x would be -1 because if you enlarge the triangle on the right to make it even with the triangle on the left, you will get the same answer. I hope this helps you out.

You basically dilate the slope of y to the slope of x by the same scale factor at which all the sides of the triangles are dilated or increased/decreased by.

Hi! Basically, the problem is asking us to find the values of a, b, and c in the equation $f(x)=a x^{2} +bx+c$ . Since we have three unknowns, we just need three equations. We can find these equations by using the data in the table.

First let's plug x = 0 and f(x) = 0.
$0=0+0+c$
$c=0$

Now that we know c, it's time to pick two more pairs. Let's plug-in (2,78) and (4,152)

$78=4a+2b$
$152=16a+4b$

Before proceeding with the process of eliminating one variable, let us first reduce both equations to their lowest terms. We divide the first equation by 2 and we divide the second one by 4.

$39=2a+b$
$38=4a+b$

Next, we subtract equation 2 from equation 1.

$1=-2a$
$a=-0.5$

Finally, we substitute the value of a to equation 2 to get the value of b.

$38=4(-0.5)+b$
$b=40$

Therefore, the function should be $f(x)=-0.5 x^{2} +40x$
