Question

What is the equation of the line that passes through the point (4, 8) and has a slope of 0?

Answer 1

y=8.

Explanation:

1) if according to the condition slope=0, then the slope-interception form of the required equation is: y=i, where i - interception;

2) if according to the condition the point (4;8) belongs to the required equation, then the required equation is: y=8
