Answer:
y = -2x - 4
Step-by-step explanation:
Formula is y = mx + b where m is the slope and b is the y-intercept
(1, -6) (-3, 2)
The slope is -2
y = -2x + b
So let's find b, insert 2 for y and -3 for x to find b
2 = -2(-3) + b
2 = 6 + b
Subtract 6 from both sides to get b alone
-4 = b
We found what b equals (the y-intercept), which is -4
So, the equation is y = -2x - 4

The greatest common factor is exactly as it sounds: the greatest factors of two or more expressions.
Factorize the numbers and identify all common factors. To get the GCF multiply all common factors:
.
Common factors are: 2 and 2, their product is 2·2=4, then the greatest common factor is 4.
