Micah and Lucy are in the school play.

Micah memorizes 12 lines of the script the first day and 10 lines each day after that
Lucy memorizes 8 lines of the script the first day and 12 lines each day after that
Make a graph to represent the total number of lines each has memorized after each day

Here is a graph representing the total number of lines Micah and Lucy have memorized after each day:

Day 1:
Micah: 12 lines
Lucy: 8 lines

Day 2:
Micah: 22 lines (12 + 10)
Lucy: 20 lines (8 + 12)

Day 3:
Micah: 32 lines (22 + 10)
Lucy: 32 lines (20 + 12)

Day 4:
Micah: 42 lines (32 + 10)
Lucy: 44 lines (32 + 12)

Day 5:
Micah: 52 lines (42 + 10)
Lucy: 56 lines (44 + 12)

Note: The y-axis represents the total number of lines memorized and the x-axis represents the number of days.

Is it possible to show a coordinate grid for the answer

Certainly! Here is a coordinate grid representing the total number of lines Micah and Lucy have memorized after each day:

Day 1: (1, 12) Micah: 12 lines, Lucy: 8 lines

Day 2: (2, 22) Micah: 22 lines, Lucy: 20 lines

Day 3: (3, 32) Micah: 32 lines, Lucy: 32 lines

Day 4: (4, 42) Micah: 42 lines, Lucy: 44 lines

Day 5: (5, 52) Micah: 52 lines, Lucy: 56 lines

On the coordinate grid, the x-axis represents the number of days and the y-axis represents the total number of lines memorized.
