Ive been trying to understand this problem for like a day and i dont :( an explanation for this would be nice if that’s possible!

Step-by-step explanation:

If you look closely you could see that every equation is put in order. But it goes, ( 1,2.5) (2,4.2) (3,?)

you have to find out the third days mile.

So you have to try and find the answer by 4.2-2.5= 1.7. so add 1.7 to 4.2.

so you're answer is (3,5.9)

Step-by-step explanation:

You solve this equation to get the form y<mx+b. First you add 3x to isolate y on the left side. Then you divide by -2 to get just y. This leaves you with y<-3/2x-3. The y-intercept would be (0,-3) and the slope would be -3/2.
