Matching Slope to Graph

Find the slope-intercept equation

• y = 2x + 3

• y = -2x +3

• y = ¹/₂ x+3

• ^{y = -1}/₂ x+3

What is the equation of a line when m = -3 and b = 5?

• y = -3x + 5

• y = -3x - 5

• y = 5x + 3

• y = -5x - 3

Just a few reminders about graphing in slope-intercept form. Make sure both the slope and the y-int match the equation!

• Oh yeah!

• I already knew that!

• That is brand new information!

• Huh?
