What is the slope of the line through the points (-2,-1) and (8,-3)?

- 1/5

Step-by-step explanation:

Slope of a line passing through two points can be calculated as:

The given points are (-2, -1) and (8, -3). Using the values in above formula, we get:

Thus the slope of the line through the given points is -1/5. So 2nd option gives the correct answer

The correct answer is second option

-1/5

Step-by-step explanation:

Points to remember

The slope of line passing through (x₁, y₁) and (x₂, y₂) is given by,

Slope = (y₂ - y₁)/(x₂ - x₁)

To find the slope of given line

Here, (x₁, y₁) = (-2, -1) and (x₂, y₂) = (8, -3)

Slope = (y₂ - y₁)/(x₂ - x₁) = ( -3 - - 1)/(8 - -2)

 = (-3 + 1)/(8 + 2) = -2/10

 = -1/5

Therefore the correct answer is second option -1/5

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
