GCF stands for greatest common factor so if u have a problem like let's say, "What is the gcf of 36 and 90?" all u do is go down your multiples table and write them all down till 36 you will get 9 and if u take 10×9 it equals 90. For LCM all you do is go down your multiples table and find the least number that is the same with each other.
Step-by-step explanation:
a) substitute x values:
6-2(0) = 6
6-2(1) = 4
6-2(2) = 2
6-2(3) = 0
6-2(4) = -2
6-2(5) = -4
b) rewrite equation as y=-2x+6.
this shows a negative slope with a y-intercept of 6.
c) 3=6-2x
-6 -6
-3 = -2x
divide both sided by 2
-3/-2 = x
3/2=x
