Answer:
Step-by-step explanation:
Note the shiding squares ( 12 of 16) represent 3/4. And you are taking a quarter of that. The equation is
The equation in rectangular coordinates. (x - 1)² + y² = 1
<h3>What are different Coordinate Systems ?</h3>
There are many types of coordinate system depending upon the usage and ease of working , Spherical , Rectangular , Cylindrical , Polar are the examples of Coordinate System.
It is given that the equation in polar coordinates is r = 2 cosθ
To change in rectangular coordinates
The relation between polar and rectangular coordinate is
x = r cosθ and y = r sinθ
x² + y² = r²
r = 2 cosθ
r² = 2r cosθ
r² = x
so the equation in rectangular coordinate system becomes
x² + y² = 2x
x² - 2x + y² = 0
x² - 2x + 1 + y² - 1 = 0
(x - 1)² + y² = 1
This represents the equation in rectangular coordinates.

Answer:
6x - y + 7 = 0
Step-by-step explanation:
To find the equation of line passing through a point and slope of same line is given, we use formula,
y - y₁ = m ( x ₋ x₁)
where, (x₁, y₁) = (6, 43)
and m is a slope of line passing through (x₁, y₁) which is equal to 6.
Substituting all values in above formula. We get,
⇒ y - 43 = 6 ( x ₋ 6)
⇒ y - 43 = 6x - 36
⇒ 6x - y + 7 = 0
which is required equation.
