Treat the data as ordered pairs. From the table, write the Altitude as x - coordinate and the Temperature as y - coordinate.
Plot the ordered pairs as points in a coordinate plane.
The scatter plot shows a negative correlation between x and y. This means that as the x - values increased, the y - value tended to decrease, so you can fit a line to the data.
Draw a line that appears to fit the points in the scatter plot closely.
Write an equation using any two points on the line.
Substitute the values of in the slope formula .
