There will be Elizabeth and Izak record the number of miles they bike each day. The line plots show the distances they each biked for 5 days. How much greater was the shortest distance Izak biked than the shortest distance Elizabeth biked in 1 day?

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
