Answer:
y = x - 1 (third answer choice)
Step-by-step explanation:
From the given we see immediately that the slope of this line is -1. The slope of a line perpendicular to this one is +1, which is the negative reciprocal of -1. The slope-intercept form is y = mx + b. To find b, the y-intercept, we make the following substitutions: m = -1, y = -2, x = -2:
-2 = +1(-2) + b, or +1 = 2 + b, or b = -1
and so the desired equation is y = x - 1 (third answer choice)
Given:
The width of a rectangle is x centimeters and its length is (x+ 2) cm.
To find:
The expression for the perimeter of the rectangle.
Solution:
We know that, perimeter of a rectangle is

We have,
Width = x cm
Length = (x+2) cm
Putting these values in the above formula, we get




Therefore, the required expression for the perimeter of the rectangle is (4x+4) cm.
