Question 185250: I need the coordinates for the equation y=1/2x-4. I know my slope is 1/2. I think my y intercept is -4. also once i find my first coordinate, to find 2 more coordinates (do i move down 1 and over 2 to the left) or (move up 1 and over 2 to the right)or both. Please help me so i can understand how to do the rest of my problems.

------------------------------------
The slope is always (change in y)/(change in x)
----------
You slope is 1/2.
So as x goes 2 to the right, y goes up 1.
--------------------------------------------
You have the intercept (0,-4)
You increase x by 2 and increase y by 1 to get (2,-3)
You do it again and get (4,-2)
Again gives (6,-1)
And finally (8,0) which is the x-intercept.
