Q. A line that includes the points (7,2) and (−2,u) has a slope of 1. What is the value of u?u = ____
Calculate Slope: We are given two points on the line: (7,2) and (−2,u), and the slope of the line is 1. We will use the slope formula to find the value of u.Slope (m)=(x2−x1)(y2−y1)1=(−2−7)(u−2)
Simplify and Solve: Now we will simplify the denominator and solve for u.1=−9u−2To get rid of the fraction, we multiply both sides by −9.1×(−9)=−9u−2×(−9)−9=u−2
Isolate Variable: Next, we will isolate u by adding 2 to both sides of the equation.−9+2=u−2+2−7=u
