I'll give brainliest if you show your work. mia’s work to find the slope of a trend line through the points (3, 10) and (35, 91) is shown below. mia's work step 1: 3-35/ 10-91 step 2: -32/ -81 step 3: 32/ 81 what was the first error that mia made? mia simplified incorrectly and made the slope positive. mia subtracted in the wrong order. mia switched the numerator and the denominator. mia used subtraction instead of addition.

Mia switched the numerator and the denominator.

Step-by-step explanation:

The slope formula is given by:

Where we have two ordered pairs:

P1 = (x1, y1)

P2 = (x2, y2)

Given is : Mia’s work to find the slope of a trend line through the points (3, 10) and (35, 91)

Step 1:

If we compare the formula with Mia's step, we can see that she switched the numerator and the denominator.

Hence, the error made is : Mia switched the numerator and the denominator.

10% of increase is the final answer! : )

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!
