2. It's not a polynomial. It's linear?

EDIT: or is it 5/(2x) ?

Oh sorry I'm not that good with terms, its just a normal line
4. A polynomial can be linear if it wants to be.

You know it is a straight line (Do you know it's a straight line? It is a multiple of x plus a constant, this is always a straight line), so you just need to plot two points, say at x=0 and x=1, then draw the line passing through them.

Then it's y=2.5x + 1.75. You know how to draw this...

How would I sketch the line: y= 5/2x - 7/4 .

I know it would have a gradient of 2.5, but I'm not sure how to go about doing it
Let y = 0 and solve for x to calculate the x-intercept.
Let x = 0 and solve for y to calculate the y-intercept.

It's obviously a straight line, because it's a linear equation (no x^2 or y^3 or xy or anything like that).

And you're basically done. A straight line which passes through the two points you worked out.

A linear equation is a type of polynomial (specifically, a polynomial of order 1) is it not?
7. Thanks for the help, I managed to do it now .

I can see where this conclusion is drawn from. I guess linear is just a special case...
