Question

Complete the equation of the line whose slope is -2−2minus, 2 and yyy-intercept is (0,-8)(0,−8)left parenthesis, 0, comma, minus, 8, right parenthesis.

Answer 1

Answer:

$y = - 2x - 8$

Step-by-step explanation:

The equation of a line with slope, m and y-intercept , b is given by

$y = mx + b$

From the question, the given line has slope -2.

This implies that:

$m = - 2$

The y-intercept is given as (0,-8).

When we compare to (0,b), we have b=-8.

Therefore the equation is

$y = - 2x + - 8$

When we simplify, we get:

$y = - 2x - 8$
