HOW TO GRAPH x + 2y ≥ -6

 The graph is attached (See explanation).

Step-by-step explanation:

The Slope-Intercept form of the equation of the line is:

Where "m" is the slope and "b" is the y-intercept.

Given inequality:

You need to solve for "y":

You can identify that the line is:

Which slope and y-intercept are:

To find the x-intercept, substitute into the equation and solve for "x":

Then, you know that the line passes through the points (0,-3) and (-6,0), so you can graph it.

The symbol indicates that the line is solid and you must shade the region above the line.

So, you get the graph attached.

0 is its x and y coordinate

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
