What is the equation of the line that passes through the points (4, 7) and has a slope of o?

If your slope is Zero, then you know that your line will be a horizontal line crossing the y-axis at a specific value. If one of the of the points on that line is is (4,7) then you can draw a horizontal line through that point.  Notice that when you do that the line only crosses the y-axis at the point y=7. Hence your equation y=7

Helpful Hint

Slope = 0, Horizontal line, equation is y = a #

Slope = Undefined, vertical line, equation is x = a #

Step-by-step explanation:

translate k to n and reflect across the line containing jk.
