First you need to rearrange the equations.
A. will turn into Y=2x-3
B. will turn into Y= 2x+3
C. will turn into Y=-2x+1
D. will turn into Y= -2x-1
The equation that fits that graph is letter A.
The reason is because the Y intercept or where the line crosses on the y axis is -3 which you can see fits the first equation.
You also know because the slope of the first equation is 2, and -3 plus 2 is -1 which is the point they marked for you (1,-1)
Hope this helps :)
