Question

How do you find the y-intercept of a table?

Answer 1

Make x=0, therefore y=-2+(-1x0)

Explanation:

x| y= -2-1x | (x,y)

--------------------------

0| y= -2-1= -3•0=0 | (0,0)

---------------------------

1| y= -2-1= -3•1= -3 | (1,-3)

---------------------------

2| y= -2-1= -3•2= -6 | (2,-6)

So now you have your points, (0,0), (1,-3), (2,-6) . You can always make it easier by just

drawing out a table like above. Just replace the x with any number you want and work out the problem y = -2-1x . Then with the number you chose, replace the x in the problem so you can solve it.
