Answer:
-1/3
Step-by-step explanation:
Slope is rise over run which is -1 over 3
let t = number of three-point shots
let f = number of free throw shots
t + f = 9 (he made a total of 9 shots altogether)
3t + 1f = 23 (number of shots multiplied by their point value)
substitution method: t = 9 - f
3(9 - f) + f = 23
27 - 3f + f = 23
-2f = -4
f = 2
find 't': t + 2 = 9
t = 7
c. 2+2 is 4 - 1 thats 3 quick mafs
