What is the slope of the line that passes through the points (1, −3) and (3, −5)
2 answers:
Answer:
Slope = -1
Step-by-step explanation:
Use the following formula:
slope (m) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (1 , -3)
(x₂ , y₂) = (3 , -5)
Plug in the corresponding numbers to the corresponding variables. Simplify:
m = (-5 - (-3))/(3 - 1)
m = (-5 + 3)/(3 - 1)
m = -2/2
m = -1
The slope of the line is -1.
~
For this case we have that by definition, the slope of a line is given by:

We have as data the following points:

Substituting the values:

Thus, the slope is -1.
Answer:
The slope is -1

Answer:
1/9
Step-by-step explanation:
The ratio of areas is the square of the scale factor for linear dimensions.
Area(y)/Area(x) = (1/3)^2 = 1/9
