Q. Use point-slope form to write the equation of a line that passes through the point (−8,7) with slope 2 .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 2, and the point (x1,y1) is given as (−8,7).
Substitute Values: Substitute the slope and the point into the point-slope form equation.Using the slope m=2 and the point (x1,y1)=(−8,7), we substitute these values into the point-slope form equation:(y−7)=2(x−(−8))
Simplify Equation: Simplify the equation.We need to simplify the equation by distributing the slope and removing the double negative in the x term:(y−7)=2(x+8)
Check Final Equation: Check the final equation for any possible simplification or errors.The equation (y−7)=2(x+8) is already in the simplest form and there are no mathematical errors.
