Question

write an equation of a line parallel to y=3x+4

Answer 1

A line parallel to y = 3x + 4 will have the same slope as y = 3x + 4.

Answer 2

ok so should I use y=mx+b

Answer 3

yes, y = 3x + 4 has a slope of 3.

So any equation with a slope of 3 will be parallel to y = 3x + 4.

Let me see you write such an equation.

Answer 4

y=3x+3 would that work?

Answer 5

Yeah.

Answer 6

sure

Answer 7

or y = 3x - 78,312

Answer 8

You just have to change the b.

Answer 9

okay thank you now what about perpendicular lines
y=3x+4

Answer 10

slope changes
Opposite reciprocal
change the sign, then flip the numerator and the denominator.

Answer 11

okay so how do I do that just change the 3x to -1/3x+4

Answer 12

oh changing the sign means changing it to either negative or positive

Answer 13

You got it :D

Answer 14

Oh okay so it would be y=-1/3x+4?

Answer 15

Yeah

Answer 16

oh okay thanks

Answer 17

You're welcome
