Question

Which graph represents 2x-5y< 15

Answer 1

Answer:

Step-by-step explanation:

Rewrite 2x-5y< 15 as follows:  Add 5y to both sides.  Then 2x < 15 + 5y.

Next, subtract 15 from both sides:  2x - 15 < 5y.

Finally, divide all terms by 5:           (2/5)x - 3 < y

Now find the y-intercept of this line.  Let x = 0.  Then y = -3.  Plot (0, -3) on graph paper.  Now, starting at (0, -3), move your pencil point 5 spaces to the right and 2 spaces up.  Plot this new point, (5, -1).  Now draw a dashed line through both (0, -3) and (5, -1).  Shade the area ABOVE this dashed line.
