Question

PLEASEEEEEEEEEE HELPPPPPP!



Using a sheet of graph paper, solve the following system of equations graphically. Be sure to show any work, use a straight edge, and be neat. When you are finished, enter the solution set in the box below and turn in your graph paper to your teacher.

x + y = 0
x - y + 2 = 0

Answer 1

rewrite equation so it is in "y=" form
x+y=0 [subtract x from both sides]
y=-x

x-y+2=0 [add y to both sides]
x+2=y

next, graph these two equations
remember that y=mx+b
b is y-intercept, that means, its where the line will cross the y axis

Answer 2

x = -1
y = 1

Answer 3

gohan, you should know better than to give answers, she needs the training

Answer 4

First take the line x+ y = 0 & find the x intercept and y intercept . To find x - intercept put y =0 in equation x+y = 0 and to find y - intercept put x= 0, & with the help of these intercepts draw the line , similarly do for second equation x - y + 2 = 0 & draw the line .Then point of intersection of these lines is solution ....
