**Got supplies? Paper, graph paper, pencils…**Slope-intercept Mark Moss - Valencia College 2011**OBJECTIVES: Where we are going to:**Define slope-intercept form. Rewrite standard and slope-intercept forms. Graph lines from various data. Slope-intercept rate of change plus y-intercept Mark Moss – Valencia College 2011**y**3x + 2 Graphing the Slope-intercept form x**y**-2 Compare & contrast 3x + 2 x**y**1/4x + 5 Visualizing the Slope-intercept form x 1/4x - 5**y**1/4x + 5 Visualizing the Slope-intercept form x -1/4x - 5**y**1/4x + 5 Visualizing the Slope-intercept form x -4x - 5**5x + 10y = 200**5x + 10y = 200 Rewriting standard form to slope-intercept form? 5x + 10y = 200 5(0) + 10y = 200 10y = 200 y= 20 (0,20) 5x + 10y = 200 5x + 10(0) = 200 5x = 200 X= 40 (40,0) 5x + 10y = 200 ( add -5x) -5x+5x+10y = -5x+200 10y = -5x +200 (multiply 1/10) ( y = x + 20 m = 0 – 20 / 40 – 0 = -1/2**y**How do we graph this?
