Graph the inequality. 3x+4y<12?

Question

Graph the inequality. 3x+4y<12?

Answer 1

We need to get y by itself:

3x + 4y < 12

4y < -3x + 12

y < -³/₄x + 3

 

So that is what you need to draw on your plane. Remember, with a < sign, you use a dotted line because the values do not actually equal what is on the line. Also, since it's 'less than,' you shade in everything below since those values are smaller.
