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.

ijlal · Answer

the white line is of y=3x+1 the other is y=-x+2

anonymous · Answer

how do you make those graphs?

ijlal · Answer

they both do not intersect at origin you can see that in the graph so option 4 is wrong the rest 3 options are right but the best is option 1 that they both intersect each other so option 1 would be your answer for the best description of these equations :)

Its a software called graphmatica download it from download.com

ooh okay can you help me with another one please?

anonymous · Answer

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

ijlal · Answer

The first Step is correct 
 2x + 4 = 3x + 1 
equate both equations to find the intersection point or in other words the solution set of the equation :)
