Which graph represents 2x-5y<15?
disa [49]

Answer:

Step-by-step explanation:

First view 2x-5y<15 as the equation 2x - 5y = 15.  Find the x- and y-intercepts and plot them:  

x-intercept:  let y = 0 and find x:  x = 15/2.  Plot (0, 15/2).

y-intercept:  Let x = 0 and find y:  y = -3.  Plot (0, -3).

Draw a dashed line through these two points.  Shade the area BELOW this line.
