Please help me and my daughter

a. Linear

Step-by-step explanation:

The difference is equal between y- values (0.480)

So it is linear change and linear function

Linear

Step-by-step explanation:

The hypothese is the function is linear. Lets prove it .

If we divide the difference of 2 any function's values by the difference of the corresponding argument's values we will get the same ratio 0.48(for instance 19.210-18.250=0.96 delete be 2-0=2 will get 0.48)  .

Lets  calculate any other pair of y (function) and x ( argument) :

(20.170-18.730)/(4-1)=1.44/3=48 as we can see we'll get the same ratio 0.48.

That means that function is linear

abde or 1,2,4, 5 is the answer

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
