Q. Complete the equation of the line through (−9,−9) and (−6,0). Use exact numbers.y=
Find Slope: Find the slope of the line using the formula m=x2−x1y2−y1 where (x1,y1)=(−9,−9) and (x2,y2)=(−6,0).
Point-Slope Form: Use the point-slope form of the equation of a line, y−y1=m(x−x1), substituting the slope m=3 and one of the points, for example, (−9,−9).
Simplify Equation: Simplify the equation from the previous step to get it into slope-intercept formy=mx+b.
Finalize Simplification: Finalize the simplification to get the equation in slope-intercept form y=mx+b.
