slope is -10−10

Explanation:

If you have 2 points (x_1,y_1)(x1,y1) and (x_2,y_2)(x2,y2), then your slope or gradient will be m=(y_2-y_1)/(x_2-x_1)m=y2−y1x2−x1

Therefore, m=(-1-9)/(10-9)=-10m=−1−910−9=−10

color(blue)(" Slope " = m = -10 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)Slope =m=y2−y1x2−x1

(x_1, y_1) = 910, -1), (x_2, y_2) = (9,9)(x1,y1)=910,−1),(x2,y2)=(9,9)
