Answer:
A
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 )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 4) ← 2 points on the line
m =
=
=
= 2
The line crosses the y- axis at (0, 4 ) ⇒ c = 4
y = 2x + 4 → A

Answer:
Option D
Step-by-step explanation:
Formula to be used,
Scale factor = 
By this formula,


L =
= 77 inches
Similarly, width of the the dilated rectangle = 
= 35 inches
Perimeter of the new rectangle = 2(Length + width)
= 2(77 + 35)
= 224 inches
Option (D) will be the correct option.
