Q. Use point-slope form to write the equation of a line that passes through the point (2,10) with slope −1 .Answer:
Recall Point-Slope Form: Recall the point-slope form of a line's equation. The point-slope form of a line's equation is given by: y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line.
Identify Slope and Point: Identify the slope (m) and the point (x1,y1) given in the problem.The slope m is given as −1, and the point (x1,y1) is given as (2,10).
Substitute into Equation: Substitute the slope and the point into the point-slope form equation.Using the slope m=−1 and the point (2,10), we substitute into the equation: y−10=−1(x−2).
Check for Errors: Check the equation for any simplification or errors.The equation y−10=−1(x−2) is already in the correct point-slope form and does not require further simplification. There are no math errors.
