Exploring Slope Intercept Form

What is a linear function?

• A function with multiple graphs

• A function whose graph is a line

• A function whose graph is a curve

• A function with no graph

Which form represents a linear equation?

• ax + by = c

• ax^2 + by = c

• ax + by^2 = c

• ax^2 + by^2 = c

What is the x-intercept of a line?

• The point where the line crosses both axes

• The point where the line does not cross any axis

• The point where the line crosses the x-axis

• The point where the line crosses the y-axis

How is the y-intercept written?

• (x, y)

• (0, y)

• (x, 0)

• (0, 0)

What does 'm' represent in the slope-intercept form y = mx + b?

• The y-intercept

• The slope of the line

• The constant term

• The x-intercept

If the slope is 1/5 and the y-intercept is -3, what is the equation of the line?

• y = 5x - 3

• y = 1/5x - 3

• y = -1/5x - 3

• y = 1/5x + 3

What is the first step in graphing an equation in slope-intercept form?

• Find the x-intercept

• Draw the line

• Identify the y-intercept

• Identify the slope

If the slope is positive, how do you move on the graph?

• Move down and to the left

• Move down and to the right

• Move up and to the left

• Move up and to the right

For the equation y = 2x + 1, what is the y-intercept?

• (0, 1)

• (2, 0)

• (1, 0)

• (0, 2)

If the slope is -2/5, how do you move on the graph?

• Move up 2 units and over 5 units to the right

• Move up 2 units and over 5 units to the left

• Move down 2 units and over 5 units to the right

• Move down 2 units and over 5 units to the left
