doy 60 puntos, pero Ayúdame a resolverlas

Answer 1

a)

y = - 3x

x = 0, y = - 3(0) = 0

x = 1, y = - 3(1) = - 3

x = 2, y = - 3(2) = - 6

x = 3, y = - 3(3) = - 9

x = 4, y = - 3(4) = - 12

b)

y = 2x / 3 + 2

x = 0, y = 2(0) / 3 + 2 = 0 + 2 = 2

x = 1, y = 2(1) / 3 + 2 = 2 / 3 + 2 = 0.67 + 2 = 2.67

x = 2, y = 2(2) / 3 + 2 = 4 / 3 + 2 = 1.33 + 2 = 3.33

x = 3, y = 2(3) / 3 + 2 = 2 + 2 = 4

x = 4, y = 2(4) / 3 + 2 = 8 / 3 + 2 = 2.67 + 2 = 4.67

c)

y = - 2x + 1

x = 0, y = - 2(0) + 1 = 0 + 1 = 1

x = 1, y = - 2(1) + 1 = - 2 + 1 = - 1

x = 2, y = - 2(2) + 1 = - 4 + 1 = - 3

x = 3, y = - 2(3) + 1 = - 6 + 1 = - 5

x = 4, y = - 2(4) + 1 = - 8 + 1 = - 7

d)

y = 2x - 3

x = 0, y = 2(0) - 3 = 0 - 3 = - 3

x = 1, y = 2(1) - 3 = 2 - 3 = - 1

x = 2, y = 2(2) - 3 = 4 - 3 = 1

x = 3, y = 2(3) - 3 = 6 - 3 = 3

x = 4, y = 2(4) - 3 = 8 - 3 = 5

e)

y = 3x - 2

x = 0, y = 3(0) - 2 = 0 - 2 = - 2

x = 1, y = 3(1) - 2 = 3 - 2 = 1

x = 2, y = 3(2) - 2 = 6 - 2 = 4

x = 3, y = 3(3) - 2 = 9 - 2 = 7

x = 4, y = 3(4) - 2 = 12 - 2 = 10

f)

y = (x + 4) / 2

x = 0, y = (0 + 4) / 2 = 4 / 2 = 2

x = 1, y = (1 + 4) / 2 = 5 / 2 = 2.5

x = 2, y = (2 + 4) / 2 = 6 / 2 = 3

x = 3, y = (3 + 4) / 2 = 7 / 2 = 3.5

x = 4, y = (4 + 4) / 2 = 8 / 2 = 4
