For perpendicular questions, you need to find the reciprocal of the slope and change it's sign.

I sent a picture to show you what I mean

With your graph questions, remember

rYse over run

\frac{y}{x}

This is for your slope. for example, with number 19, go up 7 over the right 4(Because it's a positive number) starting from the y-intercept but also backtrack so it's a line and your y-intercept, b, the number after the slope is the point where the line meets the y- axis. So for number 19, you would plot a point at (0, -4)

I'm not entirely sure that's how the slope things go (The actual slope not the y-intercept) so I would suggest asking your teacher about that.

Sorry I couldn't help more! I just hope this makes you understand just a little bit more :)

Kylie correctly understood that it is a difference of squares, but she did not determine the product correctly.

How to factor 6x^2-48x-120
mamaluj [8]
Hello there!

Simply find a common term that they all have!

So they can all be divided by 6, right? So let's take a 6 out.

6 (x^2-8x-20)

Now factor the terms in the parenthesis!

6 (x-10) (x-2)

^ This is NOT your answer!!

Tip: When looking at (x^2-8x-20), look at the middle term. (-8x). Since it's negative, either (x-10) or (x-2) can be negative.

Which one is negative? Well, is the 8 positive or negative? Since the 8 is negative, the parenthesis bigger number (x-10) will be negative!

So it'll be:

6 (x-10) (x+2)

ALWAYS double check your answer by foiling! :)

Hope this helped!
