Q. The points (2,z) and (3,−10) fall on a line with a slope of −8. What is the value of z?z = ____
Identify Given Points and Slope: Identify the given points and slope.We have the points (2,z) and (3,−10) and a slope of −8.We will use the slope formula, which is (y2−y1)/(x2−x1)=slope.
Plug Values into Formula: Plug the values into the slope formula.−8=3−2−10−zSimplify the denominator.−8=1−10−z
Simplify Denominator: Solve for z.Multiply both sides by 1 to get rid of the denominator.−8×1=(−10−z)×1−8=−10−z
Solve for z: Isolate z.Add 10 to both sides of the equation.−8+10=−10+10−z2=−z
Isolate z: Solve for z by multiplying both sides by −1.2×−1=−z×−1−2=z
