The plot below shows the ages of residents at Oak Creek Assisted Living. The black dots represent residents in the east wing, and the gray dots represent residents in the west wing. Use the plot to answer the following question.

There isn't a plot

Step-by-step explanation:

x - 2y = 4

Step-by-step explanation:

The equation of a line in standard form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, 0 ) ← coordinates of intercepts

m = = = ,

Note the y- intercept c = - 2, thus

y = x - 2 ← in slope- intercept form

Multiply through by 2

2y = x - 4 ( subtract 2y from both sides )

0 = x - 2y - 4 ( add 4 to both sides )

4 = x - 2y, that is

x - 2y = 4 ← in standard form
