The slope is –3, and the y-intercept is Negative one-half.
The slope is –3, and the y-intercept is Three-halves.
The slope is 3, and the y-intercept is Negative one-half.
The slope is 3, and the y-intercept is Three-halves.

Answer 1

The table gives points (−1, −3/2) and (0, 3/2). Slope = (3/2 − (−3/2)) / (0 − (−1)) = (3) / 1 = 3. The y-intercept is y(0) = 3/2.

So: slope = 3, y-intercept = Three-halves.
