Plot the following lines on the graph above:

A)         y = x+2

B)         y = {\Large\frac{1}{4}}x-1

C)         y = -x-1

D)         y = -x+4

Use your graph to estimate (to 1 d.p.) the solution to the following equations:
1)       x+2=-x-1
2)       x+2=-x+4
3)       {\Large\frac{1}{4}}x-1=-x-1
4)       {\Large\frac{1}{4}}x-1=-x+4
