Q. Find the slope of the line passing through the points (−9,9) and (5,9)
Identify Coordinates: Identify the coordinates of the two points.The first point is (−9,9), which means x1=−9 and y1=9.The second point is (5,9), which means x2=5 and y2=9.
Use Slope Formula: Use the slope formula.The slope m of a line passing through two points (x1,y1) and (x2,y2) is given by m=x2−x1y2−y1.
Substitute Coordinates: Substitute the coordinates into the slope formula.m=5−(−9)9−9
Perform Subtraction: Perform the subtraction in the numerator and the denominator. m=5+90
Simplify Expression: Simplify the expression. m=140
Calculate Slope: Calculate the slope.m=0Since any number divided by a non-zero number is 0, the slope of the line is 0.
