Answer:
Step-by-step explanation:
to find the slope you do, [tex]m=y{2}-y{1}/x2-x1\\ m=16/-4\\ m=-4\\[/tex]The new equation is going to be y=-4x+b, to find b you plug one of the points you are given and solve for b. [tex]-6=-4(1)+b\\-6=-4+b\\-2=b[/tex]the you use the info and you should get y=mx+b, which in this case is y=-4x-2
Hope that helps for the other one.
