Question

The points in each table lie on a line. Find the slope of the line.

Answer 1

Answer:

1

Step-by-step explanation:

Given table:

     x      -1    1   3   5

     y      -2   0   2  4

Unknown:

Slope of the line  = ?

Solution:

Each x and y pair on the table lies on the line. Therefore, we can use them to find the slope;

  Slope  = $\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$  

 let us take;

x₁ = -1        x₂ = 3

y₁ = -2        y₂ = 2

Insert the parameters and solve;

   Slope = $\frac{2 - (-2)}{3- (-1)}$   = $\frac{4}{4}$   = 1

The slope of the line is 1
