# What Do You Do to an Equation if You Want Your Graph to Shift Up?

## Transcript

Hi, I'm Rachel, and today we're going to be going over what do you do to an equation if you want your graph to shift up. Well if you're graphing a line then you're going to want to increase the Y intercept. So that the graph literally shifts up. So let me show you what I mean. Here is our graph here, and let's say we have, this is at point 1 right there. So this is going to look like y=x+1, right? It intersects right at zero 1. And we want this to shift up, maybe to something like that. So we are going to increase the Y intercept which is the "b" which is this right here, right? I'm assuming you guys know slope intercept form, y=mx+b. So, let's say this is 1, this is 2, 3, 4, 5, 6, 7. So it's just going to look like y=x+7. We don't have to change the slope right? Because we're literally shifting the line, it's the same slope, but it's just shifting up. So we're changing the Y intercept. If we wanted to shift it down we'd make it a lower Y intercept. Y=x-7 right? To put it down here, shifting it down. And that's how you shift your graph. Without graphing you can just here see the equation, right? Just like that. I'm Rachel and thank you for learning with me today.
