Q. The points (6,5) and (5,u) fall on a line with a slope of 8. What is the value of u?u = ____
Slope Formula Application: We know the formula for the slope m between two points (x1,y1) and (x2,y2) is:m=x2−x1y2−y1We are given the slope m=8 and the coordinates of two points (6,5) and (5,u).Let's plug these values into the slope formula to find u.
Solving for u: Using the slope formula:8=5−6u−5Now we need to solve for u.
Simplify Denominator: First, simplify the denominator:8=−1u−5To get rid of the fraction, we multiply both sides by −1:8×(−1)=u−5
Multiplying Both Sides: Now, perform the multiplication on the left side:−8=u−5Next, we add 5 to both sides to solve for u:−8+5=u
Calculating u Value: Finally, we calculate the value of u: −3=u So, the value of u is −3.
