Answer: y = -x/2 -4
Step-by-step explanation:
I hope you mean perpendicular to y= 2x - 5 and that passes through (2, -5)
Take the reciprocal of the original slope. Reverse the slope to negative. Substitute the values of the given coordinates for x and y in the base equation y =-x/2 and solve for "b" the new y-intercept.
-5 = - (2)/2 +b
-5 = -1 +b
-5+1 = b
-4 = b
