Find and interpret the slope of the line (9,6)(2,20)

Question

Find and interpret the slope of the line containing the given points (9,6)(2,20)

Answer 1

slope = "rise over run" = change in y values divided by x values = (20-6)/(2-9)= 14/-7 =-2

slope=-2 for points

(9,6), (2,20)

negative sign means the line is downward sloping.

-2 means

as x increases by 1 y decreases by 2

y decreases twice as much as x increases, as you move along the line

it may help to plot & graph the points and line
