13, I believe? Sorry if you get it wrong
Let this guide you through
This is the same as any math problem you may have solved before.
First, start by isolating the x on one side. I will choose to keep the coefficient positive, so I will add x to both sides.
6>2x+2
Subtract 2
4>2x
Divide by 2
2>x
Or
x<2
Partial Product is for multiplication and regrouping is for addition.
Hope that helped:)
I will take you the steps to obtain the slopes passing two points
step 1 : list the parameters

step 2: Apply the equation to obtain the slope between two points
