use intercepts to graph each equation
1) 4x +y = -4
2) x-y = -1
please help
1) 4x +y = -4
2) x-y = -1
please help
-
1) 4x+(0) = -4
4x=-4
4/4 = 1
x=1 (x intercept)
4(0)+y=-4
y=-4 (y intercept)
(1,-4) is your answer
2) x-(0)=-1
x=-1
y is the same
(0,0) is your answer- i also noticed that every point on that graph had opposing x and y coordinates such as (1,-1) (3,-3) etc
