y=-11/14x
1) Let's plug it into that considering that -11/14 is the slope of the line that passes through the origin (0,0)
y=mx +b Plugging point (0,0) and slope m=-11/14 we have
0 =-11/14(0) +b
b= 0
2) Then we can write the equation of the line, as y=-11/14x note that since b=0 there is a linear coefficient b=0.
