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 our Y intercept is negative six.

Now, y 5x, 14 if I'm trying to take that minus five X y 5x move it from left 15 to, y 5x, 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.

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. Let's subtract 10x from both sides. We get an inconsistent result. It's a positive five. So they're parallel lines. So let's do it. And it's negative 5x plus 8, so 1, 2, 3, 4, 5, 6, 7, 8. So it just looks like that.

And instead of writing a y there, and I've said it multiple times already, we can write a negative 5x plus 8. And it has the same slope as this first line. They don't intersect.

So let me just graph these just to make it clear. Posted 4 months ago. Now we have 10x minus 10x. 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. That's this first equation right over there. So they've set it up for us pretty well. It's right over there. And then it has a very steep downward slope. See our results. Explanation for Question 8 From the Math No Calc Section on the October Sat Now in question number eight were asked, which of the following is the graph 2 of this equation, right? This is an inconsistent result.
