Q. A line that includes the points (−6,10) and (−7,z) has a slope of 9. What is the value of z?z=___
Identify Points and Slope: Identify the points and slope given in the problem. Points: (−6,10) and (−7,z). Slope: 9. Use the slope formula: Slope = x2−x1y2−y1.
Use Slope Formula: Simplify the denominator and solve for z. 9=−1z−10.
Simplify and Solve: Simplify the equation to find z. −9=z−10.
Calculate Final Value: Calculate the final value of z. z=1.
