Coordinate Plane and Proportional Relationships

The video tutorial covers the basics of the coordinate plane, including labeling axes and plotting points. It explains proportional relationships and how to determine if a graph is proportional by checking if it passes through the origin. The lesson includes practical applications and examples, followed by details on homework and assignments.

What is the name of the point where the x-axis and y-axis intersect?

• Midpoint

• Intersection

• Origin

• Vertex

Which axis is labeled as the horizontal line on a coordinate plane?

• Y-axis

• Z-axis

• X-axis

• W-axis

If a point is at (3, -2) on a coordinate plane, which direction do you move from the origin?

• Right 3, Down 2

• Left 3, Up 2

• Right 3, Up 2

• Left 3, Down 2

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

• Move up or down

• Start at the origin

• Draw a line

• Label the axes

How can you determine if a relationship is proportional on a graph?

• If the line passes through the origin

• If the line is vertical

• If the line is horizontal

• If the line is diagonal

What is the formula for the constant of proportionality?

• y = mx + b

• y = kx

• y = x/k

• y = k + x

In the formula y = kx, what does 'k' represent?

• Variable

• Slope

• Intercept

• Unit rate

If a robotic vacuum cleans 16 square feet in one minute, how much will it clean in 10 minutes?

• 160 square feet

• 32 square feet

• 48 square feet

• 80 square feet

What should you do if you accidentally label inside a box on a coordinate plane?

• Ignore the mistake

• Draw a new box

• Erase and label on the line

• Leave it as is

What tool is necessary for the virtual learning assignment on scale drawings?

• Calculator

• Ruler

• Compass

• Protractor
