Identify Point-Slope Form: Identify the point-slope form of a linear equation.The point-slope form of a linear equation is given by the formula y−y1=m(x−x1), where m is the slope of the line and (x1,y1) is a point on the line.
Substitute Slope and Point: Substitute the given slope and point into the point-slope form.We are given the slope m=81 and the point (−7,9). Substituting these values into the point-slope form, we get:y−9=(81)(x−(−7))
Simplify the Equation: Simplify the equation.Since x−(−7) is equivalent to x+7, we can rewrite the equation as:y−9=(81)(x+7)This is the equation of the line in point-slope form.
