find the slope of the line that passes through the pair of points (6.5, 10.5) and (–9.5, 7)
i dont get what im doing wrong i followed the last steps you did
(7 - 10.5) = -2.5 -9.5 - 6.5 = 16 -2.5 / 16 = -5 / 32 slope = -5/32 Use the formula (Y2 - Y1) / (X2 - X1) Remember, two negatives make a posi.tive
my answer is is supposed to be one of the following a. 4.57 c. 40 b. 0.22 d. –1.14
how do i change that to a decimal
10.5 - 7 should be 3.5 not 2.5 sorry
so it's 3.5 / 16 = ~ 0.22
