Question

Date

Answer 1

Answer:

The line is:

• y = 1/2x + 4

The student correctly plotted one point:

• (0,4)

Incorrectly plotted the second point. Instead of (2, 2) it should be:

• y = 1/2*2 + 4 = 1 + 4 = 5
• point (2, 5)

As a result the student got a negative slope and wrong line.

Correct one is attached

Answer 2
