How do I solve this. 3x-4y<12 to get it ready to graph?

Do I set it up like m=mx+b and solve for Y

Yes, you can set it up in slope-intercept form (y=mx+b), which would give you:

y>(3/4)x-3

You then graph the line with a slop of 3/4 that passes through the point (0,-3). Choose a point and test in in the equation.

Choosing (0,0) we have:

0>-3

Because this statement is true, shade the graph above the line; the section that includes (0,0)

yes you do

then plot a point on x and substitute it in the equation to get y, don’t forget that the sign

reverses when you divide a negetive number

you can also use the 0,0 as a substitute for x and y

plot 2 or 3 points and draw a line

the line should be broken because it is not equal at any point

then shade on the appropriate side, above the line if it is greater than, below if it is less than

x-2y=8 => 2y = x-8 => y = 1/2 x – 8 put at least three different values of x and get the corresponding y values. plot on graph and join them with a straight line infinitely extended on both sides. do similarly with the second equation. the point of intersection is the point whose co-ordinates satisfy the equations. nb: three points to be taken such that line joining the two points passing through the third necessarily and sufficiently represents the equation.
