Answer:
The equation of the line would be y = -2x + 3
Step-by-step explanation:
In order to find the equation of the line, start by using point-slope form with the known information.
y - y1 = m(x -x1)
y - 1 = -2(x - 1)
Now that we have this, solve for y.
y - 1 = -2x + 2
y = -2x + 3
Using the formula for the perimeter and area of rectangle, the dimensions are: Length = 19 m; width = 9 m.
<h3>What is the Perimeter and Area of a Rectangular Shape?</h3>
Perimeter = 2(length + width)
Area = (length)(width).
Let x represent the length and y the width, therefore:
2(x + y) = 56 --> eqn. 1
xy = 171 --> eqn. 2
Rewrote eqn. 1
x + y = 56/2
x = 28 - y
Substitute x = (28 - y) into eqn. 2
171 = (28 - y)y
171 = 28y - y²
171 - 28y + y² = 0
y² - 28y + 171 = 0
Factorize
(y - 9)(y - 19)
y = 9 and y = 19
Therefore, the dimensions are: Length = 19 m; width = 9 m.
