• f(x) because its rate of change is 4 while the rate of change for g(x) is 2 
• g(x) because  its rate of change is 4 while the rate of change for f(x) is 2
• g(x) because its graph appears steeper than that of f(x)
• Neither, both graphs appear to rise at the same rate

• The y-intercept of the function f(x) is less than the y-intercept of the function g(x) 
• The y-intercept of the function f(x) is greater than the y-intercept of the function g(x)
• The y-intercept of the function f(x) is equal to the y-intercept of the function g(x)
• The y-intercepts cannot be determined

• A

• B

• C

• D

Answer explanation

eliminate answer choices by y intercept even though it is not shown. where is x zero? then get slope.

• A

• B

• C

• D

Answer explanation

Find the slope of the table. Then work backwards from x=2 to where x = 0 would be. The slope is 65 and the y intercept is 620.
