The area of a square floor on a scale drawing is 81 square centimeters, and the scale drawing is 1 centimeter:2 ft.
so the original area is
A = 81 sq cm ( 2 ft / 1 cm)^2a = 324 sq ft
so the ratio of the ratio the area in the drawing to the actual area is:
r = 81 sq cm / 324 sq ftr = 1 sq cm / 4 sq ft1 sq cm : 4 sq ft

Answer:
y=-2x+5
Step-by-step explanation:
Use the equation y=mx+b
We can find the b(y-intercept) by looking at the graph
The graph crosses the y-axis at (0,5)
We can look at the slope at the graph. We can see its down 4 over 2 so the slope is -2.
Plug that into the equation y=mx+b
y=-2x+5
