Anya found the slope of the line that passes through the points (–7, 4) and (2, –3). her work is shown below. let (x2, y2) be (–7, 4) and (x1, y1) be (2, –3). m = = = the slope is . what error did she make? she simplified the denominator incorrectly. the denominator simplifies to –7. she labeled the points incorrectly. the point (–7, 4) should be (x1, y1). she used an incorrect formula. the formula should be the change in y-values with respect to the change in the x-values. she used an incorrect formula. the formula should be the sum of the x-values with respect to the sum of the y-values.

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
