Question

1 math quesiton MEDAL AND FAN!!!!!!!!!








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)

Answer 1

just graph them
go onto mathway.com

Answer 2

if you need help graphing the first one, you isolate the y

Answer 3

@AloneS what do u think?

Answer 4

see the point of intersection would be common in both lines

Answer 5

Problem:
Solve −x−y=1;y=x+3
Steps:
I will try to solve your system of equations.
y=x+3;−x−y=1
Step: Solvey=x+3for y:
Step: Substitutex+3foryin−x−y=1:
−x−y=1
−x−(x+3)=1
−2x−3=1(Simplify both sides of the equation)
−2x−3+3=1+3(Add 3 to both sides)
−2x=4
−2x
−2
=
4
−2
(Divide both sides by -2)
x=−2
Step: Substitute−2forxiny=x+3:
y=x+3
y=−2+3
y=1(Simplify both sides of the equation)
Answer:
x=−2 and y=1

Answer 6

so jst substitute the valus of y from equation 1 in 2 and get x

Answer 7

B

Answer 8

@rishavraj do u think its b?

Answer 9

If you change -x-y=1 into workable y=mx+b, you should get y=-x-1, and then you can graph both equations

Answer 10

I believe it is b
