Answer:
Y = 0x + 8
Explanation:
The slope-intercept form is: y = mx + b
m is slope
b is where the line intercepts the y-axis.
If the slope is zero, then we already have the first part of the equation, y = 0x
Next, we have to figure out the y-intercept. Because the slope is zero, the y-intercept is the same throughout the entire line. If the line goes through the point (-7, 8), then the y-intercept is 8, in all points that the line goes through.
Therefore, the equation is y = 0x + 8.
