Question

The slope of the line passing through the points (-2, 6) and (4, 6) is

Answer 1

The slope of a line can be calculated from any two points on that line.

slope=m=(y2-y1)/(x2-x1),  where (x1,y1) and (x2,y2) are two points.

In this case:

m=(6-6)/(4--2)

m=0/6

m=0

Since the slope is zero, this is just a horizontal line, specifically the line:

y=6
