Question

This table of values represents a linear function. Enter an equation in the form y=mx+b that represents the function defined by this table of values

Answer 1

Answer:

y=-2x+3

Step-by-step explanation:

m = slope = y/x = -4/2 = -2

b = y intercept = 3

Answer 2

Answer:

f(x)=-2x-4

Step-by-step explanation:

First of all, I want to say that I'm a 5th grade kid, and I'm studying linear functions in eight grade. The equation is f(x) = mx + b. The b is y intercept. Since the y is -1, we know that f(x)=mx+-1, or f(x)=mx-1. Then, we look that the x. It's 2. Then, substitute 2 for m. F(x) = 2x-1. I'm gonna do the other ones. f(x)=4x-5, f(x) = 6x-9.  We know that the x is substracting 2. The y is subtracting 4. So the rule is f(x) = -2x-4
