Question

The line y = —x + 4 passes through which of the following points?

• A. (2,2)
• B. (5,4)
• C. (1,2)
• D. (3,6)

Answer 1

Answer:

A. (2,2)

The equation of the line is:

y = -x + 4

A point lies on the line if it satisfies this equation (i.e., substituting (x) gives the correct (y)).

So any correct point must satisfy (x + y = 4).

Examples of points on the line include:

• (0, 4)

• (1, 3)

• (2, 2)

• (3, 1)

• (4, 0)

Answer = (2,2)
