Given:
The graph of a line.
To find:
The point-slope form of the given line.
Solution:
From the given graph it is clear that the line passes through the point (1,5) and (0,-1). So, the slope of the line is:
The slope of the line is 6 and it passes through the point (1,5). So, the point slope form of the line is:
Therefore, the point-slope form is , slope is 6 and the point is (1,5).
Let r be a radius of a given circle and α be an angle, that corresponds to a sector.
The circle area is
and denote the sector area as
.
Then
(the ratio between area is the same as the ratio between coresponding angles).
.
160cm3
2/5 - 1/4 = 8/20 - 5/20 = 3/20
(3/20)t = 24
t = 160
we know that
The internal angles of the triangle 
are
Angles
The internal angles of the triangle 
are

therefore
the answer is
