Answer:
b. slope: 2; y-intercept: -20
Step-by-step explanation:
The y-intercept is the first point in the table, where x=0. That eliminates choices A and D.
The slope is the difference in y divided by the difference in x. Using the first and second points in the table, this is ...
(-10 -(-20))/(5 -0) = 10/5 = 2
The slope is 2; the y-intercept is -20.
