Answer
Table: The slope is -2.
x y
1 2
2 0
3 -2
4 -4
Work Step by Step
Using the function f(x) = 4-2x, plug in a value of x to calculate corresponding values of y. To graph the function, plot the x and y values on a coordinate grid. In this case, as we can tell from the graph (as x increases by 1, y decreases by 2) the slope is 2. Note: f(x) = 4-2x is equivalent to f(x) = -2x + 4, and we can confirm the slope of -2 from the a value, which equals -2.
