Q. Write the equation of the line that passes through the points (−4,9) and (2,−8). Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line.Answer:
Calculate slope: Calculate the slopem of the line using the formula m=x2−x1y2−y1. We have the points (−4,9) and (2,−8). Let's denote (−4,9) as (x1,y1) and (2,−8) as (x2,y2). Using the slope formula: m=2−(−4)−8−9m=6−17m=x2−x1y2−y10
Write point-slope form: Write the point-slope form of the equation of the line.The point-slope form is y−y1=m(x−x1).We can use either of the two points for (x1,y1). Let's use the first point (−4,9).Substitute m=−617 and the point (−4,9) into the equation.y−9=(−617)(x−(−4))y−9=(−617)(x+4)
Simplify equation: Simplify the equation if necessary.In this case, the equation is already in point-slope form and does not need further simplification.
