Question

Which is the graph of the linear function that is represented by the equation y = one-half x minus 2?
On a coordinate plane, a line goes through points (negative 1, 0) and (0, 2).
On a coordinate plane, a line goes through points (negative 2, 0) and (0, 1).
On a coordinate plane, a line goes through points (0, negative 2) and (4, 0).
On a coordinate plane, a line goes through points (0, negative 2) and (1, 0).

Answer 1

The third one: the line through (0, −2) and (4, 0).

Check: y-intercept is (0, −2). Slope = (0 − (−2)) / (4 − 0) = 2/4 = 1/2, so the equation is y = (1/2)x − 2.
