Question

Find an equation of the line containing the given pair of points.
(4,1) and (12,3)

I got y=1/4x + 1 for the answear

Answer 1

How do i find the answear to this problem?

30 over 150 = n over 100

what is n?

Answer 2

slope = slope
(y - 1)/(x-4) = (3-1) /(12-4)

(y - 1)/(x-4) = 2/8 = 1/4

y - 1 = x/4 -1

y = x/4

check (note you could do this yourself)
see if (4,1) is on the line
1 = 4/4 yes
Now see if (12,3) is on the line
3 = 12/4 yes
so yes, checked

Answer 3

How do i find the answear to this problem?

30 over 150 = n over 100

what is n?

30/150 = n/100
multiply both sides by 300
2*30 = 3 n
n = 20

check
30/150 = 20/100 ?
1/5 = 1/5 check
