Answer:
y = x +
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (1, 5)
m = =
, hence
y = x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (1, 5 ), then
5 = + c ⇒ c = 5 -
=
y = x +
← in slope-intercept form
Answer:
Width of the rectangle = 17 inches
Length of the rectangle = 31 inches
Step-by-step explanation:
Let w be the width of the rectangle.
Given:
Width of the rectangle = w
Length of the rectangle = 2w - 3
Area of the rectangle
Solution:
We know that the area of the rectangle.
Now, we first find the root of the above equation.
Use quadratic formula with .
Put a, b and c value in above equation.
For positive sign
w = 17 inches
So, width of the rectangle is 17 inches.
Length of the rectangle.
Length = 31 inches
So, length of the rectangle is 31 inches.
Therefore, width and length of the rectangle is 17 inches and 31 inches.
