hi
how do i Find the slope of the line that passes through each pair of points.

(1, 2) and (−3,2)
To find the slope of the line passing through (1, 2) and (−3, 2), we use the slope formula:

m = (y2 - y1)/(x2 - x1)

where (x1, y1) = (1, 2) and (x2, y2) = (−3, 2)

Plugging these values into the formula, we get:

m = (2 - 2)/(-3 - 1)

m = 0/-4

m = 0

Therefore, the slope of the line passing through (1, 2) and (−3, 2) is 0.
a person is 100% correct I just took the assessment and got a 100.
