PLEASE HELP If you do answer plz answer all of them. Thank you! I will choose brainiest ;)

7-9 you need to plug numbers into the formula y= mx+b where you plug the plots in M and B.

Step-by-step explanation:

I don't have a graph to plot 1-3 on but all you need to do is plot them and answer if they are parallel, perpendicular, or neither. (The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.) (In math, parallel means two lines that never intersect — think of an equal sign.) And if they don't fit either then its NEITHER

true

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3
