Coordinate Plane and Slope Mastery

The video tutorial reviews the coordinate plane, including axes and quadrants, and explains how to plot points. It covers identifying linear and non-linear points using tables and calculating the slope of a line from a graph using the rise over run method. The tutorial also demonstrates how to determine slope without a table, directly from a graph.

What is the horizontal axis on a coordinate plane called?

• x-axis

• z-axis

• y-axis

• w-axis

In which quadrant would you find a point with a positive x value and a negative y value?

• Quadrant IV

• Quadrant I

• Quadrant II

• Quadrant III

What is the first step in plotting a point on a coordinate plane?

• Identify the y value

• Identify the x value

• Label the quadrants

• Draw the axes

How can you tell if a set of points forms a linear pattern?

• The points form a circle

• The points form a straight line

• The points form a square

• The points form a triangle

What is the rate of change if the y values decrease by 3 and the x values decrease by 1?

• 3

• -3

• -1

• 1

When calculating the rate of change, which value goes on top?

• Sum of x and y

• Change in y

• Difference of x and y

• Change in x

What is another term for the rate of change in a graph?

• Vertex

• Slope

• Axis

• Intercept

How do you calculate the slope of a line from a graph?

• Rise over run

• Difference of x and y

• Sum of x and y

• Run over rise

If a line goes down to the right, what is the sign of its slope?

• Undefined

• Positive

• Negative

• Zero

What is the slope of a line that rises 2 units and runs 3 units to the left?

• 3/2

• -2/3

• 2/3

• -3/2
