### Find the slope of a line through the points (-8,16) and (-4,-4).

###### What You Get

Given: Point 1 = (-8,16) Given: Point 2 = (-4,-4) -4-16 Slope = m = ----- -4--8 -20 m = --- 4 m = -5 Finding b = Y-Intercept y = mx + b Slope-Intercept Equation b = Y-Intercept Using Point 1: (-8,16) 16 = -5 * -8 + b b = 16 - 40 b = -24 y = -5x -24 Slope-Intercept form using y = mx + b 5x + y = -24 Standard-Form

Intersection: (-22/13, -72/13)
