The equation of a line is y= -1/2x - 1 what is the equation of the line that is perpendicular to the first line and passes through the point (2, –5)?

y=2x-9 or D

Step-by-step explanation:

To get the slope of the perpendicular line, you find the negative reciprocal.  The negative reciprocal of -1/2 is 2.

Then, you need to find the y-intercept.  Considering the line has to pass through the point (2,-5), you can use the slope to find that the y-intercept is -9.
