Atelephone company charges a fixed monthly rate plus a rate per minute of usage. the company charges $155 for 100 minutes of usage and $245 for 200 minutes of usage. an equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). which of the following best describes the steps to draw the graph of y against x?

a) draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 0.9
b) draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 1.1
c) draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 1.1
d) draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9

The answer is D.

Step-by-step explanation:

As said in the problem, we are labeling the total minutes used x and the total monthly income as y. This means that in the graph we will be making the y-axis should represent the total monthly charges, and the x-axis should represent the total minutes.

Thus the graph should go through points (100,155) and (200,245) and its slope is:

The answer would be D according the the question at hand.

to have more of what you want like money

step-by-step explanation:

save it by not spending on unnecessary stuff and have more

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
