Question 454100: Write the slope-intercept equation for the line that passes through (-90, 75) and is (a) parallel and (b) perpendicular to 2x-15y=5.

y = (2 x)/15-1/3
slope is 2/15
parallel will have the same slope
75=-90*2/15+b
solve for b
perpendicular will be - 15/2
y=mx+b
75=-15*(-90)/2+b
solve for b
