    y=mx+b slope intercept form where m is slope and b is y-intercept if line increasing then slope would be `positive ` if line is decreasing then slope would be `negative` slope = rise over run (count how many units its going up from the y-intercept and then how many units to the right ) b(y-intercept) is a point where line intersect at `y-axis`

    right side where x values are positive so rise =-4 and run =2 slope = rise over run replace rise with -4 and run with 2 and then divide

    \[\rm slope =\frac{ rise }{ run }=\frac{ -4 }{ 2 }\]
