Jasmine hikes at a rate of 2 miles per hour.
She wants to know how far she was from home when she started hiking.
Is the initial value shown in the table or on a numbered gridline?
Yes
No

Answer 1

Distance = 2t + b. From the table, at t = 2, distance = 12, so 12 = 2(2) + b → b = 8.

She was 8 miles from home when she started. That initial value is not in the table (table starts at t = 2) but it is on a numbered gridline (Yes).
