What is the equation of a line that passes though the points (0,85) and (4,8)?

The equation of line is:

Step-by-step explanation:

Given points:

and

To find the equation of the line.

Solution:

In order to find the equation of the line we will first find the slope of the line.

The slope of a line passing through points and the slope can be given as:

Plugging in the given points to find the slope of the line.

Equation of line can be written in point slope form as:

where  is a point on the line.

Using point (4,8)

Multiplying both sides by 4.

Using distribution:

Subtracting both sides.

Subtracting 308 both sides.

Multiplying each term with -1.

Thus, equation of line is:

answer:

your answer is: c. 196 7/8 in^3.

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!
