Complete the equation of the line through (3,-1) and (4,7) PLZ I really need help
I´m at this type of things

8x-25=y

Step-by-step explanation:

All we need is slope. (y2-y1)/(x2-x1). Now we just substitute values--(7+1)/1=8

Now we can plug in the slope as m, so

8x+b=y

Now all we have to do is plug in a point value and find B.

24+b=-1

Subtract 24 from both sides

b=-25

CHECK

32-25=7

Correct

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
