Q. Use point-slope form to write the equation of a line that passes through the point (13,12) 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.
Substitute Given Point and Slope: Substitute the given point and slope into the point-slope form.Given point (x1,y1)=(13,12) and slope m=−31, we substitute these values into the point-slope form equation.(y−12)=−31(x−13)
Check for Simplification: Check the equation for any possible simplification. The equation (y−12)=−31(x−13) is already in the correct form and does not require further simplification.
