Q. A line with a slope of −5 passes through the points (−3,w) and (−2,−9). What is the value of w?w=___
Set up slope equation: Step 1: Use the slope formula to set up the equation. The slope formula is (y2−y1)/(x2−x1). Here, (x1,y1)=(−3,w) and (x2,y2)=(−2,−9).Slope = (−9−w)/(−2+3)
Set slope equal to −5: Step 2: Since the slope of the line is given as −5, set the expression equal to −5.−5=1−9−wMultiply both sides by 1 to simplify:−5=−9−w
Solve for w: Step 3: Solve for w. Add 9 to both sides of the equation.−5+9=−9+9−w4=−w
Final solution for w: Step 4: Multiply both sides by −1 to solve for w.w=−4
