Question

Write a line parallel to y=4x-7 and goes through point (4,7)

Answer 1

parallel line m=4
y-y1=m(x-x1)
y-7=4(x-4)
y-7=4x-16
y=4x-9

Answer 2

Hey what about write a line perpendicular to y=4x-7 and goes through (0,-7)

Answer 3

perpendicular line m= -1/4
put the x and y coordinates like I just did and input m to -1/4 solve it and bla bla
