Q. Use point-slope form to write the equation of a line that passes through the point (−5,3) with slope −31.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 −31, and the point (x1,y1) is given as (−5,3).
Substitute Values: Substitute the slope and the point into the point-slope form equation.Using the slope m=−31 and the point (x1,y1)=(−5,3), we substitute these values into the point-slope form equation:(y−3)=−31(x−(−5))
Simplify Equation: Simplify the equation by distributing the slope on the right-hand side.(y−3)=−31(x+5)
Check for Simplification: Check the equation for any possible simplification.The equation (y−3)=−31(x+5) is already in the simplest form and correctly represents the point-slope form of the line.
