Write an equation of a line that passes through the point (8,2) that is (a) parallel and (b) perpendicular to the graph of the equation

Question

y= 4x +3

Answer 1

Parallel line has same gradient,m.from equation of line,m=4 y-y1=m(x-x1) y-2=4(x-8) y-2=4x-32 y=4x-30 b)m2=-1/m1=-1/4 y-2=-1/4(x-8) 4y-8=-x+8 4y=-x+16
