irga5000 [103]

Answer:

y=5x+1

Step-by-step explanation:

If you look closely at each side, you will see that the x increases by one and the y increases by five.

To get to zero (0) from one (1), you need to substract one.

Every time one is subtracted for x, 5 is subtracted from y.

6-5=1

<u>Hope this helps :-)</u>
