Answer:
The Domain is where the line on your graph crosses the X axis.
The Range us where the line on your graph crosses the Y axis
And a arrow means it goes Into infinity
Step-by-step explanation:
Say you Have a line, it crosses the X axis at -3, your Domain would be -3!
Now say this line crosses the Y axis at -6, Your Range would be -6!
And now say if instead of the line ending at a dot after crossing -6 It has a arrow, that means you have infinity, Making your range instead of -6 it's be infinity! (If the arrow points up it's positive infinity, If the arrow points down it's negative infinity)
So for the first 2 numbers your answer would be [-3,-6] and in you have infinity itd be [-3, infinity) parenthesis isn't a error btw if you still don't get it I can just reply with a sheet I have on it

Answer:
289 messages
equation: 
graph: attached below
Step-by-step explanation:
We can write this in slope-intercept form, or 
. Since x is defined as the #of text messages, and 0.05 is the cost of a text message, 0.05 will be m. 45.5 is the base price, or the y-intercept, so it will be b.
Plugging in these numbers, we get 
now we make y = 60, since that is the total amount they have
So, they can send 290 messages for 60, but they need the bill under 60, so 1 text message less will be 289, and that's enough.
