Question

Based on the table below, identify the
slope and y-intercept of the linear
equation.

Answer 1

y-intercept: 3

slope: -3

Explanation:

The y-intercept is the point at which a line crosses the y-axis, which means that the y-intercept must be (0, y). The only value at which x is 0 is (0, 3), so the y-intercept is 3.

The definition of slope is rise over run, or:

`m=(y_2-y_1)/(x_2-x_1)`

Choose any two coordinates and replace the values in:

`m=(6-3)/(-1-0) \\m=(3)/(-1)\\m=-3`
