Question

Find an equation in point-slope form of the line with slope 3 and containing (-7,-2)

Answer 1

`\bf (\stackrel{x_1}{-7}~,~\stackrel{y_1}{-2})\qquad \qquad \qquad slope = m\implies 3 \\\\\\ % point-slope intercept \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-2)=3[x-(-7)]\\\\\\ y+2=3(x+7)`
