Answer:
2
Step-by-step explanation:
/2= 8
8+6= 14
4+3=7
14/7= 2
Y = 10 +2x . . . . . . y is dollars, x is number of cards.
Slope: -1 y- intercept: (0,8)
<span>Slope is calculate by dividing the change in y-values by the change in x-values between a pair of points.
For 7: (7-1)/(1-10) = 6/-9 = -2/3
For 8: (6.1-3.1)/(-5.5 - -2.5) = 3/-3 = -1
For 9: (5/2 - -3) / (-5 - -7/3) = 11/2 / -8/3 = -33/16. This is not an answer option, so double check the problem.</span>
