A student finds intercepts of 2x - y = 4 as (2,0) and (0,-4). They pick an arbitrary third point by setting x = 4 and computing y to be 8, then plot (4,8). Is the student's third point correct?

• A. Yes, because 2(4) equals 8.
• B. No, the correct y-value should be 4.
• C. No, the correct y-value should be -4.
• D. Yes, because the slope of the line is 2.

Answer: (B)
