Question

Im graphing some inequalities at the moment

x≤3
y≥6-3x

Now from my understanding it turns into
x=3
y=6-3x
Im getting stumped at this part im not sure if i have to turn it into y intercept form or not?

Answer 1

You have an equation in x and y, y>= 6-3x, which u want to graph, correct?

So normally you would just feed in values of x and find the y's, plot them.

The difference here is that u have a condition that x must be less than or equal to 3. so, for example you would not be able to use x=4 to get a value for y.

Does that help?

Answer 2

You lost me, so if i have y≥6-3x i need to find the slope of this correct? im pretty confused

Answer 3

Me too :-), I'm not really sure about your question.

I guess what I mostly want to know is if u are trying to graph something or calculate something? Or both?

Answer 4

let me screencap for you then

Answer 5

OK, this appears to be a graphing exercise.
