Answer:
y= 2 + 0.23x
Step-by-step explanation:
Giving the following information:
A text message plan costs $2 per month plus $0.23 per text.
<u>First, we need to structure the total cost formula:</u>
<u></u>
y= total cost
x= number of text messages
y= 2 + 0.23x
<u>Now, we can calculate the total cost for any number of text:</u>
x= 200
y= 2 + 0.23*200
y= $48
One. that is the definition of a line.
Through any two points, there is exactly one line.
It looks like it’s the second one because i did the question
Answer:
the second choice is correct
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 9 is in this form
with slope m = 
• Parallel lines have equal slopes, hence
y =
x + c ← is the partial equation of the parallel line
To find c substitute (- 8, - 18) into the partial equation
- 18 = - 6 + c ⇒ c = - 18 + 6 = - 12
y =
x - 12 ← equation of parallel line
