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

Answer 1

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
\(y-y_1=-\frac{1}{m}(x-x_1)\)

Answer 2

so y- (-7) = -1/m(x-2)
