Question

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

Answer 1

Answer:

y-intercept: 3

slope: -3

Step-by-step 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:

$m=\frac{y_2-y_1}{x_2-x_1}$

Choose any two coordinates and replace the values in:

$m=\frac{6-3}{-1-0} \\m=\frac{3}{-1}\\m=-3$
