Good question sir but idk
Answer:
Slope = -9/2
Two points are (-2,9) and (2,-9)
Step-by-step explanation:
The two points the equation should go through are (-2,9) and (2,-9), (Dark Green and Light Blue).
The slope-intercept is calculated using the two points above;
-9 - 9 = -18
2 - (-2) = 4
Slope = -18/4 or -9/2
Hope this helps!

300 messages would have to be sent or received in order for the plan to cost same each month.
Step-by-step explanation:
Given,
Cost per month = $30
Per text sent or received charges = $0.10
Let,
x be the number of texts sent or received.
A(x) = 0.10x+30
A comparable plan costs = $60 per month
Text messages are unlimited.
B(x) = 60
For the two plans to cost equal;
A(x) = B(x)

Dividing both sides by 0.10

300 messages would have to be sent or received in order for the plan to cost same each month.
