Step #1 get slope m. m=1/2 from the equations using point-slope form y-y1=m(x-x1)

Step #2 For the perpendicular line, you have to find the perpendicular slope. The reference slope is m = 1/2, and, for the perpendicular slope, I'll flip this slope and change the sign. Then the perpendicular slope is m = – 2/1 or just -2.

Step #3 Substitute m into y-y1=m(x-x1) using the point given (-2,1)

y-1 =-2(x- (-2) )=>

y-1 = -2 (x +2 ) =>

y= -2x -4 + 1=>

y=-2x + 3 is the equation of the line perpendicular to y=1/2x + 1

I would expect that my explanation is easy to follow and if you might need any future help please email me to set up a lesson even if it's for one hour a week to work on any difficulties that you may have. I wish you the best of luck in your studies.

Thanks,
