Tabitha is trying to find the equation of a line perpendicular to y= 1/2x - 5 in slope-intercept form that passes through the point (2, -7). which of the following equations will she use.
1. ) = 1/2(x-2)
2.y-2=1/2())
3.)=-2(x-2)
4.y-2=-2())

Step-by-step explanation:

The point-slope form of an equation of a line:

m - slope

Let .

================================================

We have the equation of the line:

Therefore

Put it and coorinates of the point (2, -7) to the equation of a line

in the point-slope form:
