Hi,

making the choice... after determining the equation of the line....

the standard slope-intercept form for an equation of a line y = mx + b  

where m is the slope and b the y-intercept.  

line with a slope of 3 

y = 3x + b  Using ordered pair Pt(-1,2) to solve for b

2 = 3*-1 + b

5 = b

y = 3x + 5

answer D would be the correct choice
