Please look in your text book for this problem Statement

Treat the data as ordered pairs. From the table, write the goals as x - coordinate and the assists as y - coordinate.

Plot the ordered pairs as points in a coordinate plane.

The scatter plot shows a positive correlation between x and y. This means that as the x - values increased, the y - value tended to increase, so you can fit a line to the data.


Draw a line that appears to fit the points in the scatter plot closely.

graph the equation y=1.25x+11.5

Write an equation using any two points on the line.

Substitute the values of in the slope formula .


To write the line equation, we can use either of the two given points.

Consider the point .

Substitute in point-slope form equation or .

Apply distributive property: .

Add 29 to each side.

The line equation is .

Substitute the value of in the above equation.

Subtract 11.5 from each side.

Divide each side by 1.25.

Cancel common terms.


The missing value is 7, the equation is and its graph isgraph the equation y=1.25x+11.5
