Answer:
Slope = 2
Y-intercept = -4
Step-by-step explanation:
The slope of a function is found by finding the change in the y-values and dividing it in the change in x-values.
The change in y-values is 2 because that is the difference between each given data point. The change in x-values is 1 for the same reason.
The slope would be 2/1 which is just 2.
The y-intercept can be found by setting up the function in slope-intercept form (y=mx+b) and using the given data to solve for b. The point I chose to do this with was (2,0)
y=mx+b
y=2x+b
0=(2*2)+b
0=4+b
b=-4
So the slope is 2 and the y-intercept is -4.
