Explanation Given: A pair of point ( − 3 , − 6 ) , ( 1 , 5 ) Concept Used: Slope: In math the slope is the measure of the steepness of a line or slope is defined from left to right. A positive slope: A line is moving from left to right and moving up, it a positive slope. A line with positive slope is always moving upward. A Negative Slope: A line is moving from left to right and moving down go down, it is a negative slope. A line with negative slope is always moving downward. Horizontal Line: A Horizontal line is one the goes Left to right, parallel to the x-axis of the coordinate plane. A Horizontal line has zero slope. Vertical line: A vertical line is one the goes straight up and down, parallel to the y-axis of the coordinate plane. A vertical line has no slope. Or put another way, for a vertical line the slope is undefined. Calculation: The slope ‘m’ of the line through points ( x 1 , y 1 ) and ( x 2 , y 2 ) is given by: m = y 2 − y 1 x 2 − x 1 ; x 2 ≠ x 1 Given points are: ( − 3 , − 6 ) , (
