Y=-2/3x-2
Slope:-2/3
Slope intercept form is y=mx+b. So you have to isolate the y.
Subtract 2x from both sides
3y=-2x-6
Divide 3 from both sides
y=-2/3x-2
The area of sector is 1.57 m²
<u>Explanation:</u>
Given:
Radius, r = 3 m
Central angle of a sector = 1/9π radians
Area of sector, A = ?
We know:
Area of sector, A = 
where,
α is the central angle in radians
On substituting the value we get:

Therefore, the area of sector is 1.57 m²
A rhombus is a square when the angles are at 90°.
