Step-by-step explanation:
his plan includes 800 minutes for 79.99, all we need to do is calculate the cost of the extra 50mins he used and add it to 79.99. this is ((850-800)*0.18) +79.99 and this is equal to 88.99

Answer:
A
Step-by-step explanation:
This is how I write
y=kx+m
but I have seen some write it like this:
y=mx+b
Well both of them are the same thing, I'll use the first one because I'm more comfortable with it.
y=kx+m
To find out what k
So you first need to choose two points.
I'll go for (0,-5) and (2,0)
Now you could insert k into the equation and it will look like this.
To find out what m is just pick one point and insert it into the equation. So if I pick (0,-5). 0=X therefore it should be replaced by x and -5=y therefore it should also be replaced by y.
m=-5
Try it with another point to see if you get the same answer. this time I'll pick (-6,10)
m= -5
The equation will be y=-5/2x-5)
