Question

What is the slope of a line that contains the points (1,9) and (4,3)​

Answer 1

The slope of the line is -2

To find the slope of a line using two points, there are many formulas, however the easiest one to use is (rise/run)

The rise is the difference in the Y value and the run is the difference in the X value

(9-3)/(1-4) = (6/-3) = -6/3, which can be simplified to -2

Answer 2

The slope is -2

Explanation:

To find the slope of a line when we have 2 points, we use the formula

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

= (3-9)/(4-1)

= -6/3

-2
