What is the equation of the line that passes through the point (-1,7) and is parallel to the line y= -2x-1
Answers: 1
has a slope of -2.![\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{7})\qquad \qquad \qquad slope = m\implies -2\\\\\\\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-7=-2[x-(-1)]\\\\\\y-7=-2(x+1)\implies y-7=-2x-2\implies y=-2x+5](/tpl/images/0085/0056/b0458.png)
