Q. Find the slope of the line that passes through (10,8) and (8,9).Write your answer in its simplest form.
Slope Formula: To find the slope of the line that passes through two points, we use the slope formula: slope m = x2−x1y2−y1, where (x1,y1) and (x2,y2) are the coordinates of the two points.Let's assign the points as follows: (x1,y1)=(10,8) and (x2,y2)=(8,9).Now we can plug these values into the slope formula.
Assign Points: Calculate the difference in the y-coordinates y2−y1: 9−8=1.
Calculate y-coordinate difference: Calculate the difference in the x-coordinates (x2−x1): 8−10=−2.
Calculate x-coordinate difference: Now, divide the difference in y-coordinates by the difference in x-coordinates to find the slope: slope m = −21 = −21.
Find Slope: The slope of the line that passes through the points (10,8) and (8,9) is −21. This is a proper fraction and represents the rate at which the line rises or falls as it moves from left to right.
