Question

Which has the greater rate of change (slope)

Answer 1

The slope for a would be 6/1
and then a good way to calculate the slope for b is by taking two sets from the chart and doing y₂-y₁/x₂-x₁.
So let's take (4, 2) and (6, 10). Your equation would be 10-2/6-4 which will give you a slope of 4/1 after simplifying.
So your answer will be a.
