what are the coordinates for a) 18x-9y<2 an b)x> or equl to 4y - 5?

Answer 1

Place these into standard form: y = mx + b

a) 18x - 9y <2 becomes -9y < -18x + 2

Now, divide by -9. If you do this, the sign will change around!

y > 2x - 2/9.

So, the slope is 2, the y intercept is -2/9.

When x is 0, y is -2/9. When y is 0, then y is 1/18.

b) x >= 4y-5

This becomes 4y <= x+5 and then divide by 4.

y <= x/4 + 5/4. The slope is 1/4, the y intercept is 5/4.

When x is 0, y is 5/4. When y is 0, x is -5.

Good luck!
