#9=-8, #10= -18, #11=-20

Step-by-step explanation:

For these, you need to remember that a positive*a positive is always positive, a negative * a negative is always positive, and a negative * a positive is negative.

So just do 2*4, 6*3, and 4*5 and add a negative in front of them.  

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
