Q. A line has a slope of 8 and includes the points (−1,9) and (−2,p). What is the value of p?p=___
Use slope formula: Use the slope formula: Slope = (y2−y1)/(x2−x1). Here, the slope is 8, and the points are (−1,9) and (−2,p).Calculation: 8=(p−9)/(−2+1)
Calculate slope: Simplify the denominator and solve for p.Calculation: 8=−1p−9
Isolate p: Multiply both sides by −1 to isolate p−9.Calculation: −8=p−9
Solve for p: Add 9 to both sides to solve for p.Calculation: p=1
