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 one right there. So this is going to look like y equals x plus one, right? It intersects right at zero, one. 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 equals mx plus b. So, let's say this is one, this is two, three, four, five, six, seven. So, it's just going to look like y equals x plus seven. 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 equals x minus seven, 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.
