To find the slope, you can use the equation y2-y1 divided by x2 - x1. When you plug in the numbers from the problem, the equation becomes 9-6/-3-(-9). We know that subtracting by a negative is the same as adding a positive, so the equation becomes 9-6/-3+9. When you solve this, it becomes 3/6, which can be simplified to become 1/2. I have attached an image to hopefully make this easier for you to understand because I know it’s a bit confusing written out in words (I’m sorry if the image is bad, I drew it on my phone). If there is anything that you need me to clarify, please let me know and I will be happy to help!

Please help with a math problem :/ Please show steps...<br><br> x^2 -13x = -36
Marianna [84]
X^2 -  13 x = -36 
add 36 to both sides

x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}

How do I solve 2f+10?
Scorpion4ik [409]
First of all, you want the variable to be isolated, so in order to do that, you divide in both sides. Ten divided by two is five. So f = 5.

2f + 10
---    ---
2      2

10 divided by 2 = 5
