Which system is represented by the graph?
A. y=3x-2 y=3x-1
B. y=-3x-2 y=-3x-1
C. y=1/3x-2 y=1/3x-1
D. y=3x+2 y=3x+1

A. y=3x-2 y=3x-1

Step-by-step explanation:

FRom the given graph, it can be seen that

Blue line passes through  (1,2) and (0,-1)

Red line passes through  (1,1) and (2,4)

As we know , equation of line passes through points (a,b) and (c,d) :

Then , Equation of blue line will be :

...(i)

Then , Equation of red line will be :

....(ii)

From (i) and (ii) , the required equations are :

Hence, the correct option is A. y=3x-2 y=3x-1.

answer:

step-by-step explanation:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
