What is the slope of a trend line that passes through the points open paren negative 3 comma 3 close paren and open paren 18 comma 26 close paren ?

Use the slope formula: change in y divided by change in x. From (-3, 3) to (18, 26), the change in y is 26 − 3 = 23 and the change in x is 18 − (−3) = 21, so the slope is 23/21. The correct choice is 23 over 21.
