4.3 Graphing Linear Nonproportional Relationships Using Slope and y-intercept

Lesson 4.3 Pre Algebra

4.3 Graphing Linear Nonproportional Relationships using slope and y-intercept!

Ordered Pairs (x, y); m = slope ; b = y-intercept

Multiple Choice

Given y = -x + 3/4...what is the slope?

• 1

• -1

• there is no slope

Is this a positive or negative slope?

Multiple Choice

Given y= 8x + 4, identify the slope and y-intercept

• m = 8; b = 4

• m = 4; b = -4

• m = 4; b = -8

• m = 8; b = -8

Multiple Choice

Given y = -2/3x - 9

What is the slope and y-intercept?

• m = 2/3 and b = 9

• m = -2/3 and b = -9

• m = -9 and b = -2/3

Multiple Choice

Given y = x - 17, what is the slope?

• there is no slope

• 1

Multiple Choice

Given y = -x + 2/3...

What is the slope?

• 1

• -1

• there is no slope
