What is the slope, point, x-intercept, and y-intercept?
2 answers:
As for the slope, it is the deviation of the line from a horizontal. Slope is expressed as 
.
A point is any point on the coordinate plane. Points are expressed as an ordered pair in the form (x,y). Examples include (5,) and (2,1).
The x-intercept of a line is the point at which it intercepts, or intersects, the x-axis. In other words, it is the point where the line crosses the x-axis.
The y-intercept of a line is the point where it intercepts the y-axis.

In order to find the Perimeter of the Rectangle, First we need to find the Length and Width of the Rectangle.
Distance between two points (x₁ , y₁) and (x₂ , y₂) is given by :
There are two lengths in a rectangle. Let us find any one length of the rectangle.
I'm considering the length with co-ordinates (-8 , 2) and (-2 , 10)
Here : x₁ = -8 and x₂ = -2 and y₁ = 2 and y₂ = 10
Substituting the values in the distance formula, We get :
There are two widths in a rectangle. Let us find any one width of the rectangle.
I'm considering the width with co-ordinates (-2 , 10) and (2 , 7)
Here : x₁ = -2 and x₂ = 2 and y₁ = 10 and y₂ = 7
Substituting the values in the distance formula, We get :
Perimeter of a Rectangle is given by : 2[Length + Width]
Perimeter of the given rectangle = 2[10 + 5]
Perimeter of the given rectangle = 2[15]
Perimeter of the given rectangle = 30
<u>Answer</u> : Perimeter of the given rectangle is 30 square units
