Question

the equations that are parallel and perpendicular to y = 2x - 1 and that pass through the point (4, 1)

Answer 1

perpendicular means negative inverse of slope, since initial slope is 2, the slope of the perpendicular is -1/2

so the equation you are generating will be

y=-1/2*x+b

1=-1/2*4+b

1=-2+b

b=3

y=-1/2*x+3

Answer 2

the parallel has the same slope, so

y=2*x+b

1=2*4+b

1=8+b

-7=b

y=2*x-7

Answer 3

thanks

Answer 4

sorry for the delay on that second one, didnt see you wanted both

Answer 5

its okay i kinda figured the second one out but thank you any ways.
