Write in equation in slope form of the line shown

Answers

Answer:

y=2x-5

Step-by-step explanation:

Slope intercept form is y=mx+b, with m being the slope and b being the y-intercept.

Slope is found through (y2-y1)/(x2-x1) and when the values are plugged in you get (-3-1)/(1-3) which equals -4/-2 or 2.

y=2x+b

Since b is the y-intercept, you plug in the value of the point where the line crosses over the y axis. In this case, that value is -5, so you get y=2x-5.

You found Genie hidden in a dungeon. Genie is offering two different options for you as a reward for finding him. There are two options shown for you to choose.

Which option would you choose? Explain your reasoning using the key features of exponential functions.

Answers

Answer:

The first option is

A(x) = 10000(1.05)ˣ

The second option is:

B(0) = 1000B(1) = 1100The ratio is 1.1 and the zero term is 1000

The equation for this option is:

B(x) = 1000(1.1)ˣ

Now, which option is better?

It depends on the number of x. It is assumed the genie is offering money or similar reward.

For the values of x below 50 option A is better and option B is much better for x > 50.

See the graph in the attachment, where green line represents the option A and red line is option B.
