Question 12022
Remember the slope of a line {{{ m = (y[2]-y[1])/(x[2] - x[1]) }}}

So the points are:  
y intercept = (0,5) 
x intercept = (-3,0)


{{{m = (0-5)/(-3-0)}}}
{{{ m=(-5)/(-3) = 5/3}}}


Check out the graph these points on a graph.  Starting on the x-intercept, you can measure the rise of 5 and the run of 3 to get up and over to the y-intercept.


{{{ graph (300, 300, -10, 10, -10, 10, (5/3)x + 5)}}}
