What is the origin on a coordinate plane?

• (0,0)

• (1,1)

• (1,0)

• (0,1)

In which direction do the quadrants on a coordinate plane go?

• Clockwise

• Counterclockwise

• Vertically

• Horizontally

How do you move on the coordinate plane if the x-coordinate is negative?

• Up

• Right

• Down

• Left

What is the slope of a line that rises 10 units and runs 6 units?

• 5/3

• 3/5

• 10/6

• 6/10

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

• (y2 - y1) / (x2 - x1)

• (y1 - y2) / (x1 - x2)

• (x2 - x1) / (y2 - y1)

• (x1 - x2) / (y1 - y2)

What is the x-intercept of a graph?

• The point where the graph crosses the origin

• The slope of the graph

• The x-coordinate where the graph crosses the x-axis

• The y-coordinate where the graph crosses the y-axis

What is the slope-intercept form of a line?

• x = b + my

• x = my + b

• y = b + mx

• y = mx + b

When graphing a line using the slope-intercept form, what is the first step?

• Identify the slope

• Plot the x-intercept

• Draw the line

• Identify the y-intercept
