What is the slope of a trend line that passes through the points (5, 80) and (7, 65)?

The slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.Step-by-step explanation:If the line is passing through two points (x1, y1) and (X2, y2). The slope (m) can be calculated using following formula.[tex]m = \frac{y2-y1}{x2-x1}[/tex]In this case,x1  = 5x2 = 7y1  = 80y2 =  65By putting the values in formula, we get[tex]m = \frac{(65-80)}{7-5}[/tex][tex]m = \frac{(-15)}{2}[/tex]or m = -7.5Therefore, the slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.Learn more: The following links have more information about slope Keywords: slope #learnwithBrainly
