Q. Find the slope of the line that passes through (8,7) and (1,8).Write your answer in its simplest form.
Identify Coordinates: Identify the coordinates of the two points.Point 1: (8,7)Point 2: (1,8)We will use these coordinates to calculate the slope of the line.
Recall Slope Formula: Recall the formula for the slope m of a line given two points (x1,y1) and (x2,y2):m=x2−x1y2−y1
Substitute Coordinates: Substitute the coordinates of the two points into the slope formula.Using Point 1(8,7) as (x1,y1) and Point 2(1,8) as (x2,y2), we get:m=1−88−7
Perform Subtraction: Perform the subtraction in the numerator and the denominator. m=−71
Simplify Fraction: Simplify the fraction if possible.The fraction −71 is already in its simplest form, so we do not need to simplify further.
Write Final Answer: Write the final answer as a proper fraction, improper fraction, or integer.The slope of the line is −71.
