Answer:
AB
Step-by-step explanation:
A tangent is a line that touches a circle but never goes through it. Wherever the the tangent touches is called the point of tangency and creates a perpendicular bisector (90° angle).

Step-by-step explanation:
Write in standard form.
So if x is the old cost let’s say c is the new cost
So 15%=0.15
0.15(x)=C
Answer:
The slope is +2
Step-by-step explanation:
Count the squares on the grid. Rise, how many up, then the run, how many to the right for the graphed line to cross the grid lines.
Up 2, over 1. So +2
Or by the numbers of the coordinates. (0,0) (1,2)
Y values for the rise: 2-0=2 .X-values for the run 1-0=1
2 over 1. 2/1 is +2
