The slope on a graph has exactly the same definition as
the slope of a roof. It is rise over run. For the slope of
a roof, you measure how high the roof is and divide by
the distance from the peak to the eaves, or the gutter
On a graph, the formula for this is

where the given points are (x1,y1) and (x2,y2)
If the equation of the line is in this form:
, then = slope
For instance,

The slope is
Any line parallel to this one will also
have a slope =
And to measure this slope, you would start at some point on
the line, say (0,17) which is the y-intercept, go up
2 units and see how far you went horizontally. It
should be 3 units. That's the rise over run as in a
roof.
