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.

Luzlil Villalobos. Whenever you get something like some number y 5x some other number that they're clearly not equal to, that means it's an inconsistent result, y 5x, It's an inconsistent system, and that these lines actually don't intersect. This is our y-axis.

It's parallel. The Y intercept is at negative six, 24 but we have a negative slope, right? To extend this concept, can you solve a linear system of equations with 3 unknowns? Me getting more info from the 9 year old comment than from the video:. And we're just left with 16 equals negative 2, which is crazy. This is why it's called inconsistent. Substitution will be easy here since you don't have coefficients on several of the variables. They already have y explicitly solved for up here. So it's y-intercept is negative 1. So it looks like this. What should u do if they ask u to verify it without a graph? Sarah Richer.

Every time you move forward 1, you have to go down 5. So every time we see a y in the second constraint, we can substitute it with that. Put both equations in slope y-intercept form If both have the same slope and different y-intercept then these lines are parallel and the system has no solution. Continue Reading This is why it's called inconsistent. So plus 16 is equal to negative 2. So they're parallel lines. And instead of writing a y there, and I've said it multiple times already, we can write a negative 5x plus 8. We can distribute this 2 onto both of these terms.
