Just divide 84 / 7 and will be 12
Not 100% sure what to do here can you explain?
Y2-y1/x2-x1 is slope so
9-9/14-(-20) so you get 0/34 which means there is no slope since they have the same y (the equation would be y=0x+9 therefore y=9)
Which makes sense since the equation is a straight line
IM NOT USING SQUARE ROOT SIGN... IM DOING DIVISION SIGN
