Answer:
y = x - 2
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, - 5) and (x₂, y₂ ) = (- 4, - 4)
m = =
, thus
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 6, - 5), then
- 5 = - 3 + c ⇒ c = - 5 + 3 = - 2
y = x - 2 ← equation of line
The square measures 14 by 14
so the area = 14 x 14 = 196 square inches
Double the area:
196 x 2 = 392 square inches
To find one side of the square:
= 19.80 inches (2 d.p.)
so the area = 14 x 14 = 196 square inches
Double the area:
196 x 2 = 392 square inches
To find one side of the square:
