equation of line that passes through (2, -3) with a slope of \(\frac12\) is
y + 3 = \(\frac12\)(x - 2)
y + 3 = \(\frac12\)x - 1
y = \(\frac12\)x - 4
The y-intercept is the point where x = 0 . When x = 0 ,
y = \(\frac12\)(0) - 4 = -4
When x is 0 , y is 4 . So the y-coordinate of the y-intercept is 4 .
