slope is #-10#

Explanation:

If you have 2 points #(x_1,y_1)# and #(x_2,y_2)#, then your slope or gradient will be #m=(y_2-y_1)/(x_2-x_1)#

Therefore, #m=(-1-9)/(10-9)=-10#

#color(blue)(" Slope " = m = -10#

Explanation:

Slope of an equation knowing coordinates of two points on the line is given by

#"Slope " = m = (y_2 - y_1) / (x_2 - x_1)#

#(x_1, y_1) = 910, -1), (x_2, y_2) = (9,9)#
