the question is to "rotate the line the given number of degrees a about the x-intercept and (b) about the y-intercept. Write the equation of each image"

Question

and the problem is y=2x+2 ; 90 degrees

and i dont know what to do

Answer 1

rotating the line 90° gives you a perpendicular line, thus with slope -1/2

So, find the desired intercept, and use that point and the new slope to determine the line (use the point-slope form)
