Answer:
So value of x = -1 and value of y = 1
Solution Set (-1,1)
Step-by-step explanation:
x+y =0
x-y +2 =0
We need to solve these equations to find value of x and y
x+y =0 eq(1)
Add -2 on both sides
x-y = -2 eq(2)
Add equation 1 and 2
x+y = 0
x-y =-2
______
2x = -2
x = -2/2
x = -1
Now, put value of x = -1 in equation 1
x+y = 0
-1 +y =0
Adding +1 on both sides
-1+1+y = 0+1
y = 1
So value of x = -1 and value of y = 1
Solution Set (-1,1)
We would plot the values of x= -1 and y = 1 on the graph.
Graph is attached in the figure below.
A. 16 for every 100
b. 8 for every 50
c. 1 for every 16
d. 0.5 for every 8
First, you need to know what equation form you need to write: point slope, slope-intercept, etc. Considering this case, you need to know the slope, then you must know the y-intercept, and and write like this: ( my example here is for the SLOPE- INTERCEPT form) y=slope times X + y-intercept.
