Hi Laurie,
The data point is G(-8,8)
For a horizontal line, the primary item of importance is the y-intercept, which is coincidentally the same as the y-value for every point on the line. In this case the value is 8.
The equation for the line is therefore, Y = 8.
The converse is true for vertical lines. In the case of vertical lines, the primary item of importance is the x-intercept, which is coincidentally the same as the x-value for every point on the line. In this case the value is -8.
The equation for the line is therefore, X = 8.
The equation for the line is therefore, X = 8.
I hope this helps
