## anonymous one year ago help plz Write an equation of a line perpendicular to y = 1/2x - 5 in slope-intercept form that passes through the point (2, -7). y=1/2 x - 7 y= 2x + 2 y= -2x - 5 y= -2x - 3

So, you are given an equation to determine a perpendicular line with a given point. From the given equation y = 1/2x - 5 you identify the slope. Convert the original slope into a perpendicular line slope, and by that, you take the negative reciprocal of it. $$\Large m=-\frac{1}{m}$$ Place the new perpendicular slope and the given point (2,-7)=(x1,y1) into the point slope formula $$y-y_1=-\frac{1}{m}(x-x_1)$$

so y- (-7) = -1/m(x-2) where do i go from here @Zale101
