What is the slope of the line that contains the coordinate points (8, -3) and (-2, 7)
kotykmax [81]
To find the slope of a line given the coordinates of two points, you should use the formula, Slope=y2-y1/x2-x1.

To find the slope of a line which contains the coordinates (8,-3) and (-2,7), you should substitute them into the previous mention formula.

Slope=y2-y1/x2-x1
Slope=(7--3)/(-2-8)
Slope=(10)/(-10)
Slope=-1

The slope of the line which contains the coordinates (8,-3) and (-2,7) is -1 or in other words letter A from the given choices.
