Now in question number eight were asked, which of the following is the graph 2 of this equation, right? And the equation that they give us is Y 3 minus five X is equal to negative six. If you're ever trying to take an equation and turn 7 it into a graph you want to use Y intercept form, 8 which is Y equals MX plus B. Now, 14 if I'm trying to take that minus five X and move it from left 15 to, right, that means I need to add five X to both sides, 16 because that will allow the Xs to cancel on my left, 17 leaving me with just Y and then I'll have a plus five X, 18 which I can just write, um, is five X minus six. So our slope is 21 a positive number. It's a positive five.

And we could see that by actually graphing these lines. I hope that helps make it y 5x for you. This is an inconsistent result.

And that's because these two lines actually don't intersect. So they're parallel lines. So it looks like this. Free Call. And the telltale sign of that, when you're doing it algebraically, is you get something wacky like this. This first equation is already in slope y-intercept form. And we could see that by actually graphing these lines. Continue Reading So let's do it. So when we go to the second constraint here, every time we see a y, we say, well, the first constraint tells us that y must be equal to negative 5x plus 8. Every time you move forward 1, you have to go down 5. Want to join the conversation? Flag Button navigates to signup page. So negative 5x plus 8 is equal to negative 2.

It's right over there. This is our y-axis. So these guys cancel out. Whenever you get something like some number equalling some other number that they're clearly not equal to, that means it's an inconsistent result, It's an inconsistent system, and that these lines actually don't intersect. Robin Friend. So let me just graph these just to make it clear. If you're ever trying to take an equation and turn 7 it into a graph you want to use Y intercept form, 8 which is Y equals MX plus B.
