What is the math called when you are finding the location of the Y and x Axis
Do you mean cootdinates? The x and y axis is the line of all points within the specified range for x and y
coordinates*
Yes I forgot how to work out the problem for finding the Accordance to make the lines "I'm studying for the act"
Let's work on the vocab and terminology here. If you are using a coordinate system (x- and y-axes) to locate a point, you are using coordinate geometry (sometimes called "analytic geometry" depending on what you're doing).
Okay I Do you remember shading in a part of the graph depending on which was greater than the other?, Having certain numbers on each side of the = cancel out themselves using division multiplication subtraction, Addition
It sounds like you're talking about solving inequalities, but it's hard to tell exactly what you mean.
I wish I could take a picture of what I'm trying to learn in my ACT book but I don't think I can do that. How would you Get the Y and ask Coordinates for 3X + 2Y =21 , Then decide if it's a dotted line or solid line an which have to Shade in? That's what I'm doing
Ah. Ok. It looks like you have a linear inequality. You only have an equals sign between the 3x+2y and the 21; is that supposed to be an inequality sign of some kind? ≥ or ≤? < or >?
Yes sir it is
You'll first want to solve the inequality for y, to get it into y=mx+b form, then the shading is down in the direction of the inequality: up for > and down for <.
I believe I have forgotten how to solve Y = MX+B
It's the same as any other kind of solving: You get what you're solving for on one side of the equals sign and move everything else over to the other side. You'll want to review these basics http://themathpage.com/alg/equations.htm And then review linear equations in general http://themathpage.com/alg/equation-of-a-line.htm
