Since line bisects the 1st quadrant, it will divide the quadrant into half.
Therefore, line passes through origin (0,0) and has slope of 1 (m = 1).
From slope-intercept form, equation of line is:
y - y1 = m(x - x1)
y - y1 = m(x - x1)
Putting values (x1, y1) = (0, 0) and m = 1.
y - 0 = 1(x - 0)
y = x
y - 0 = 1(x - 0)
y = x
