Question 132360
Small m refers to the slope of the line
{{{5x + y = 1}}} is the equation of a sraight line
To see the slope,m, I transform it into the 
slope-intercept form, {{{y = mx + b}}}
{{{5x + y = 1}}}
subtract {{{5x}}} from both sides
{{{y = -5x + 1}}} This is the slope-intercept form
{{{m = -5}}}
Another way to look at slope is: when {{{x}}} changes, 
how much does {{{y}}} change? The slope is
{{{m}}} = (change in {{{y}}}) / (change in {{{x}}})
Here's the plot:
{{{ graph( 600, 600, -5, 5, -8, 8, -5x + 1) }}}
