Consider the following equations:
−x − y = 1
y = x + 3
If the two equations are graphed, at what point do the lines representing the two equations intersect?
(−1, 2) (−2, 1) (1, −2) (2, −1)

Just plug in the values and see which one works

- carolinar7

SO (-1,2) ,(-2,1)

I don't know I don't get the concept

I ts just substituting in values

1,-2

- carolinar7

When you substitue in that value do both side equal the same.

Consider the following set of equations:
Equation A: y = 2x + 4
Equation B: y = 3x + 1
Which of the following is a step that can be used to find the solution to the set of equations?
2x + 4 = 3x + 1 2x = 3x + 4 2x + 4 = 3x 2x + 1 = 3x + 4

- anonymous

I got 2x+4=3x+1

Consider the following system of equations:
y = −x + 2
y = 3x + 1
Which description best describes the solution to the system of equations?
Line y = −x + 2 intersects line y = 3x + 1. Lines y = −x + 2 and y = 3x + 1 intersect the x-axis. Lines y = −x + 2 and y = 3x + 1 intersect the y-axis. Line y = −x + 2 intersects the origin.

- anonymous

Lines y = −x + 2 and y = 3x + 1 intersect the y-axis this is what I got

- carolinar7

I got none of those

I need to show my work how to get tnswer

- carolinar7

OK

- carolinar7

1.Substitute
-2x-2=x+4
2. Solve for x.
-2x-2=x+4
+2x +2x
-2=3x+4
-4 -4
-6= 3x
/3 /3
-2=x
3. Now find the y value by substituting in the x value
