​

Nonproportional linear relationships can be written in the form

  y=mx+b

This is called slope-intercept form.

​

• m is the slope and b is the y-intercept

• The y-intercept of a line is the y-coordinate of the point where the lines crosses the y-axis

Multiple Choice

What is the y-intercept shown on the graph?

• (0, -2)
• (3, 0)
• (0, 3)
• None of these.

Multiple Choice

• b=1
• b=-1
• m=1
• b=4

Multiple Choice

What would the slope of the graph be?

• Positive

• Negative

• 0

• Undefined

Multiple Choice

What is the graph's equation?

• y = 4/3x - 1

• y = -4/3x - 1

• y = 3/4x + 1

• y = - 3/4x - 1

Multiple Choice

Write an equation for the table relating x and y in slope-intercept form.

• y = 2x + 2

• y = -3x + 2

• y = 6x + 5

• y = -2x - 2

Multiple Choice

• No Solution

• One Solution

• Infinite Solutions

legs and hypotenuse

the legs ( "a" and "b") are always the two shorter sides

the hypotenuse ("c") is always the longest side

Multiple Choice

What is the final step in solving this work for c?
a² + b² = c²
3² + 4² = c²
9 + 16 = c²
25 = c²

• Divide both sides by 2
• Take the square root of both sides

Multiple Choice
