Math Problem Statement
The points represented by the table lie on a line.
A table shows the different values of x for y. X values: Negative 9, negative 5, negative 1, 3. Y values: negative 2, 0, 2, 4.
What is the slope of the line?
Solution
To find the slope of the line that passes through the points given in the table, we use the slope formula:
where and are two points on the line. Let's choose two points from the table, say and .
Step 1: Calculate the slope
The slope of the line is .
