What is the equation of the line shown in this graph?

y = 1

Step-by-step explanation:

The equation of a line is:

Here,

Finding the slope:

The slope of the line is zero, as the line is parallel to the x-axis.

Another way of finding the slope is by calculating the change in y concerning the change in x.

If we take two points that lie on the given line, like:

So, either way, we get the slope as zero.

=> m = 0

Finding the y-intercept:

The y-intercept of a line is the value of the y coordinate at which the line meets the y-axis, I.e.,

The point that lies on the line with its abscissa(x coordinate) zero.

Here, one such point is:

its y-intercept is 1.

=> c = 1

Finding the equation:

y = mx + c

y = 0 + 1

That's the equation we've been looking for!

step-by-step explanation:

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!
