Does anyone know the equation that represents the line that passes through (-3,2) and is perpendicular to the graph of x-2y=7?

    First solve for y in the equation of the line. Perpendicular means the slope of your new line will be the negative reciprocal of the slope of the first line. You'll get an equation that looks like y=mx+b. You know m (negative reciprocal), you have a point x,y (-3,2), plug them in and solve for b!

    |dw:1354397904631:dw| the slope of the other line is -2

    will that equal the equation

    so if the slope is -2 and you find slope by rise over run, the point is (-3,2) so you go down 2 and to the right 1 so the y intercept is-2

    no the equation is y=-2x-2
