Q. Use point-slope form to write the equation of a line that passes through the point (1,−19) with slope 57.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) through which the line passes.Slope (m): 57Point (x1,y1): (1,−19)
Substitute into Equation: Substitute the slope and point into the point-slope form equation.Using the point-slope form, we substitute m=57, x1=1, and y1=−19 into the equation:y−(−19)=(57)(x−1)
Simplify Equation: Simplify the equation. y+19=(57)(x−1) This is the equation of the line in point-slope form.
