Howdy! :D

Slope formula:

m= (y2-y1)/(x2-x1)

m= (7-3)/(-2-(-1)

m=4/(-2+1)

m=4/-1

The rise is 4. The run is -1. The slope is -4.

I hope this helps!

Hey there!

In this problem, we have two points, and our goal is to find the slope. In order to do this, we can use the slope given two points formula:

y2-y1/x2-x1

Now, we can plug in our values from the two points:

7-3/-2-(-1) =
4/-2+1 =
4/-1

That means -4 is our slope. The slope is defined as rise over run, so our rise is four, and our run is -1. Since slope is also defined as up/right, that negative denominator dictates the "right", and since it's negative, it goes left instead of right.

Hope this helps

Answer from: Quest

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!
