The general equation of a line is y = mx+b. The line is horizontal and the slope (m) of a horizontal line is 0. So y = 0x + b = b. Since the y intercept (where it crosses the y axis) is -1 (or b = -1) then you have the equation y = -1.
Answer: y = -1.

A rectangle has an area of 18 square feet. A similar rectangle 1

avanturin [10]

Answer:

$Ratio = 9 :80$

Step-by-step explanation:

Given

$A_1 = 18ft^2$ --- Area of smaller rectangle

$A_2 = 160ft^2$ --- Area of bigger rectangle

Required

Determine the area of the areas.

The ratio is calculated by the dividing the areas of rectangles.

$Ratio = \frac{A_1}{A_2}$

Substitute values for A2 and A1

$Ratio = \frac{18ft^2}{160ft^2}$

$Ratio = \frac{18}{160}$

Simplify the fraction

$Ratio = \frac{9}{80}$

Represent as ratio

$Ratio = 9 :80$

Hence, the ratio of the rectangles is 1 to 9
