Q. What is the slope of the line that passes through the points (2,−4) and (5,2)
Identify Coordinates: Identify the coordinates of the two points.The first point is (2,−4), which means x1=2 and y1=−4.The second point is (5,2), which means x2=5 and y2=2.No calculations are needed in this step.
Recall Slope Formula: Recall the formula for the slope of a line given two points.The slope m is the ratio of the change in y to the change in x between two points on a line.The formula for the slope is m=x2−x1y2−y1.No calculations are needed in this step.
Substitute Coordinates: Substitute the coordinates of the two points into the slope formula.Using the points (2,−4) and (5,2), we get m=5−22−(−4).No calculations are needed in this step.
Perform Calculations: Perform the calculations to find the slope.Now we calculate m=(2−(−4))/(5−2)=(2+4)/(5−2)=6/3.
Simplify Fraction: Simplify the fraction to get the final slope. 36 simplifies to 2.So, the slope of the line is 2.
