Answer:
m = 2 and b = -8.
Step-by-step explanation:
One of the most commonly used equations of straight lines is y = mx + b, where m is the slope and b is the y-intercept.
Comparing the given y = 2x - 8 to y = mx + b, we see that m = 2 and b = -8.
When the function goes 1 to the right, it goes 2 down. Therefore the direction of the function is

Hence, the function represented is
y = -2x
