The slope is –2, and the y-intercept is 6.
The slope is –2, and the y-intercept is 12.
The slope is 2, and the y-intercept is 6.
The slope is 2, and the y-intercept is 12.

Answer 1

Slope = (6 − 12)/(3 − 0) = −6/3 = −2.
y-intercept = y at x = 0 = 12.

So: The slope is −2, and the y-intercept is 12.
