How do you find slope from a table?

• put the entire table int a list and spreadsheet nd go to menu, statistics, one variable statistics

• pick two points and subtract the x values from the y values

• pick two points and put them in lists and spreadsheets. then go to menu, statistics, stat calculations, linear regression

• divide each value in the y column by a value in the x column and find the average of the answers.

How do you find slope from a graph?

• pick two points on the graph and create a list and spreadsheet from the points.

• look at where the line crosses the y axis.

• pick a point on the line and divide the y value divided by the x value.

• choose the answer choice that looks the most complicated
