Either graph the points, or you can divide x by y for each set of points and if your answers are the same, then it is linear.
Hope it helps!

Answer:
25
Step-by-step explanation:
Add 65+40 which is going to give you 105 then once you get 105 subtract 65-40 which is going to give you 25 the 105 is the total so the whole answer is 25
Answer:
no solutions
Step-by-step explanation:
y = -3x +10
3x +y = 5
Substitute the first equation into the second equation
Let every instance of y in the second equation be replaced with -3x+10
3x+ (-3x+10) = 5
Combine like terms
10 =5
This is never true so there are no solutions
(These are parallel lines with the same slope but different y intercepts)
