-4x + y = -4

When you want to find the "X" intercept, then solve for "X" by making Y = 0

When you want to find the "Y" intercept, then solve for "Y" by making X = 0.

Now that you know those two facts above, let's solve for the "X" intercept first. The "X" intercept means we solve for "X" by making Y = 0.

Here's your equation:
-4x + y = -4 Now let's plug in 0 for the Y variable and solve for "X"
-4x + 0 = -4
-4x = -4 (Now let's divide by -4 to isolate the "X")

%28-4x%29%2F-4 = %28-4%29%2F-4
x = 1

SO X = 1 when Y = 0. Our ordered pair would be: (1, 0)


Now let's do the "Y" Intercept. The "Y" intercept means we solve for "Y" by making "X" = 0

-4x + y = -4 Now let's plug in 0 for the X variable and solve for "Y"
-4(0) + y = -4 See where the 0 is in place of the "X" variable?
0 + y = -4 If you multiply -4 times 0, you will get 0.
y = -4
SO... Y = -4 when X = 0. Our ordered pair will be: (0, -4)

I hope this helps you. :-)
