Answer:
y = 2.5x
Step-by-step explanation:
y = mx + b
m=2.5 (slope) --> y=2.5x+b
coordinate : (2,5) 2 is the x coordinate, 5 is the y coordinate
to Find b, input the coordinate --> 5 = 2.5(2) + b
5 = 5 + b
0=b
y= 2.5x
This is only since it asked to solve using the point. If you look at the graph, the line intercepts the y-axis at (0,0) so b=0.

Answer:
A.m = -3
Step-by-step explanation:
This equation is written in point slope form
y-y1 = m(x-x1)
y +2 = -3(x – 7)
y - -2 = -3(x – 7)
The slope is -3 and the point is (7, -2)
Answer:
x= 11/12
Step-by-step explanation:
12x - 1 = 10
12x = 10 + 1
12x = 11, divide 11 by 12
you can't divide it evenly so leave it as a fraction.
Answer:
x=4
Step-by-step explanation:
5+2x=13
-5 on both sides
2x=8
÷2 on both sides
x=4

The arcs 
all equal to the third of the perimeter since equilateral triangle divides them like this.
So we need to find a perimeter but we are only given the area.
Let's review,
That means that from area we area able to calculate radius.
Insert the numbers,
Then use the perimeter formula to calculate perimeter since radius is known,
Now divide perimeter by 3 to get length of AB arc.
Hope this helps.
