Q. Find the slope of the line that passes through (9,10) and (2,18).Simplify your answer and write it as a proper fraction, improper fraction, or integer._____
Identify Coordinates: Identify the coordinates of the two points.Point 1: (9,10)Point 2: (2,18)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) is:m=x2−x1y2−y1
Substitute Coordinates: Substitute the coordinates of the two points into the slope formula.Using Point 1(9,10) as (x1,y1) and Point 2(2,18) as (x2,y2), we get:m=2−918−10
Calculate Differences: Calculate the difference in the y-coordinates and the x-coordinates.Difference in y-coordinates: 18−10=8Difference in x-coordinates: 2−9=−7
Calculate Slope: Calculate the slope using the differences.m=−78The slope is a negative fraction because the line goes down from left to right.
Simplify Fraction: Simplify the fraction if necessary.The fraction −78 is already in simplest form, so no further simplification is needed.
