Answer:
Ela segue esse modelo
f(x) = ax + b
Então, é só substituir os valores de x e de y na Lei de Formação
Ex: quando x=0, y=-1
y= ax+b
-1=a.0+b
b= -1
È onde a reta toca o eixo y, porque x=0
Agora, vamos usar outro par ordenado.
Quando x=2, y=3
3=a.2+(-1)
3=2a-1
3+1=2a
4=2a
a=4/2
a=2
A lei de formação é essa
a= 2; b=-1
f(x)= ax+b
f(x)=2x-1

Okay, so the possible numbers he can choose are :
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Pick out all the odd numbers and multiples of 5.
1, 3, 5, 7, 9, 10
Count how many numbers are odd and are a multiple of 5.
6 numbers are odd or are a multiple of 5.
So, out of 10 numbers, 6 are odd or are a multiple of 5,
Therefore, our answer is 6/10
If you would like it simplified, it would be 3/5
Or, as a decimal, it would be 60%
