Q. Complete the point-slope equation of the line (−9,6) through (−7,−8) and Use exact numbers.
Calculate Slope: Find the slope of the line using the two given points.The slope m is calculated using the formula m=x2−x1y2−y1, where (x1,y1) and (x2,y2) are the coordinates of the two points.Let's use (−9,6) as (x1,y1) and (−7,−8) as (x2,y2).m=−7−(−9)−8−6m=2−14m=x2−x1y2−y10
Use Point-Slope Form: Use the point-slope form of the equation of a line. The point-slope form is y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line. We can use either of the two points given, but let's use (−9,6) for this example. y−6=−7(x−(−9))y−6=−7(x+9)
Simplify Equation: Simplify the equation if necessary.In this case, the equation is already in point-slope form, so no further simplification is needed.The final point-slope equation of the line is y−6=−7(x+9).
