A line passes through the point (0, –4) and has a slope of 2003-09-03-00-00_files/i0090000.jpg. What is the equation of the line
V125BC [204]
A line always has a general equation of y = mx + b where m is the slope of the line and b is the y-intercept. Slope is the rise of one point per run and the y-intercept is the value of y when x is 0. So, the equation should be,

y = (rise/run) x - 4
