Just write the answer. No work required.

Find the equation of a line which passes through (2, 4) and has slope 0.

• y = 2

• x = 2

• y = 4

• x = 4

• y = 2x + 4

Find the equation of a line in slope intercept-form which passes through (4, 2) with slope 1/2.

Using the coordinates (-1, 1), write an equation, in point-slope form, which passes through (–1, 1) and (2, 3).

What is the equation of the line shown?

What is the standard form of y – 8 = 2(x + 3)?

• 2x + y = 14

• y = 2x + 14

• 2x – y = –14

• y – 2x = 11

• -2x + y = 14
