Best ResponseYou've already chosen the best response.1Before learning to graph inequalities, you are taught to graph lines and plot basic points. Correct?

Best ResponseYou've already chosen the best response.0I really don't know.. because I took half of Algebra like independent studies there was no teacher to explain what I was taking.

Best ResponseYou've already chosen the best response.1Let's began with the first multiple choice. y < – 4x – 2

Best ResponseYou've already chosen the best response.1Every line has an equation written similar to the slope intercept form. The slope intercept form of equation is written like this : \(\Large y=mx+b\) m stands for slopes b stands for yintercept (where the line touches the yaxis and has a x=0) and x and y are changing, while m and b are constants.

Best ResponseYou've already chosen the best response.1When we have inequalities, we'll have to try to see if from a y=mx+b perspective so we can get a sense on what line we are dealing with. To do that, you basically change any inequality symbols (>, <) to an equal sign. So, \(\large y ~<~ – 4x – 2\) Will eventually become, \(\Large y=4x2\)

Best ResponseYou've already chosen the best response.1The line is y=4x2 Is this equation already in a slope intercept form?

Best ResponseYou've already chosen the best response.0what does it mean when you have ≤ this sign

Zale101

Best ResponseYou've already chosen the best response.1If we have this, let's say \(y\le x\) That means all the y values are less than or equal to x are shaded and the line is straight and bold, not dashed. It would have been a dashed line if the symbols were just less than or greater than (<,>). But when we add an equal sign next to the inequality, than it becomes a bold line. So, when graphing it, it will become like this.dw:1439489341719:dwdw:1439489445470:dw

Best ResponseYou've already chosen the best response.1As you can see from the graph i drew, all the yvalues on the bottom of the line is shaded because the inequality is y is less than or equal to x.

Best ResponseYou've already chosen the best response.1And the line is bold, not dashed, because there's an equal sign with the inequality.

Best ResponseYou've already chosen the best response.1Yes, you drew the Cartesian graph correctly. Now, you can go ahead and draw the line. It's okay if you make any mistakes because you have me to correct it for you.

Best ResponseYou've already chosen the best response.1My first point is (0,2) You can pick whatever you want for x, i chose 0 and got 2 for y, and you can choose 1 if you want.

Best ResponseYou've already chosen the best response.0so u just choose any number

Zale101

Best ResponseYou've already chosen the best response.1Plotting points is all about choosing whatever number you want for x, and plug that number for x into the equation to get for y. Just like how I chose 0 and plugged that into y=4(0)2 and got 2 for y. Yes, you can choose any number.

Zale101

Best ResponseYou've already chosen the best response.1Yes. So we have two points. (0,2) and (2, 10) Can you plot these two points on this graph i drew? dw:1439491250235:dw

Zale101

Best ResponseYou've already chosen the best response.1Yes. So, our two points that we plotted we \((0,2)\) and \((2,10)\) We plotted those. The line is dashed. dw:1439492035470:dw

Zale101

Best ResponseYou've already chosen the best response.1Nope. It doesn't doe A is incorrect. We know from the graph that the line is dashed, that means the inequality is show as < or > We also know that the line is positive because it continuously goes up to the right on the positive direction. The first choice y < – 4x – 2 went downwards because it was negative 4x2. We also know that the graph is less than than or < because the graph is shaded on the bottom of the line.
