Question

Ребята пж с обьяснением срочно дам 30 баллов​

Answer 1

у = kx + b

1) e, d

y = 3x - 5

k = 3

b = - 5

k + b = 3 - 5 = - 2

kb = 3 × (-5) = - 15

2) a, b

y = 2x + 7

k = 2

b = 7

k + b = 2 + 7 = 9

kb = 2 × 7 = 14

3) c

y = - x + 4

k = - 1

b = 4

k + b = 4 - 1 = 3

kb = - 1 × 4 = - 4
