Given the coordinates of the points passing through a line:
Let's name the given coordinates:
x1, y1 = -8,6
x2, y2 = 0,6
In determining the slope (m), we will be using this formula:
Let's plug in the coordinates in the formula to be able to get the slope (m).
Therefore, the slope of the line (m) = 0. The line is a horizontal line and has no slope.
The same thing works at question 17 at x1,y1 = -5,6 and x2,y2 = -5,10.
