i found the slope i just need help finding the y intercept please

Question

anonymous · Answer

−2    −2 
   2     10 
   6      22

anonymous · Answer

the left side is x axis and right is the y axis

hartnn · Answer

so use the slope intercept form
$\large y =mx+c$

you found out m = slope
you just need c

hartnn · Answer

plug in any one point from the 3 given
say 
x=2, y=10
in that equation :)

anonymous · Answer

what is c exactly? and how do i find it?

hartnn · Answer

c is the y-intercept of the line

anonymous · Answer

okay so then my equation is 10 = (3)2 + c then i try to bring c to one side?

hartnn · Answer

plug everything you know in 
y = mx+c

x=2, y=10
m = you already found out

the only unknown is c :)

hartnn · Answer

and yes

anonymous · Answer

ok so 10 = (3)2 + c 
10 = 6 + c
 -6   -6 
4 = c so y intercept is 4
