Answer:

The equation of the line that passes through the point (-2, 0) and has a slope -2 is:

  •  [tex]y = -2x - 4[/tex]

The graph of the line equation [tex]y = -2x - 4[/tex] is also attached.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

  • m is the slope
  • b is the y-intercept

Given that the equation of the line that passes through the point (-2, 0) and has a slope of -2.

so we have

  • slope m = -2
  • point (-2, 0)

The first step we need to do is to determine the y-intercept of the line.

so substituting m = -2 and (-2, 0) in the slope-intercept form of the line equation to determine the y-intercept b

[tex]y = mx + b[/tex]

[tex]0 = -2(-2) + b[/tex]        ∵ (x, y) = (-2, 0)

[tex]0 = 4 + b[/tex]

[tex]b = -4[/tex]

Thus, the y-intercept b of the line is: b = -4

The second step is to substitute b = -4 and m = -2 in the slope-intercept form of the line equation

[tex]y = mx + b[/tex]

[tex]y = -2x + (-4)[/tex]

[tex]y = -2x - 4[/tex]

Therefore, the equation of the line that passes through the point (-2, 0) and has a slope -2 is:

  •  [tex]y = -2x - 4[/tex]

The graph of the line equation [tex]y = -2x - 4[/tex] is also attached.
