Question 295019
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")


{{{(-4x)/-4}}} = {{{(-4)/-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. :-)
