Linear Function Attributes Flip Cards

Linear Function Attributes

The point where the line crosses the y-axis is (0,3).

The line does not pass through the origin (0,0)

The zero is the x-intercept (-6,0)

What is the zero of the function?

What is the y-intercept?

Does this relationship represent a direct variation?

-6

No

f(0) = 3 and f(4) = 5 so f(0)<f(4)

f(-4)= (-4,1)

f(-4)=

f(0) = f(4)

False

Linear Function Attributes

y=-2x

What is the y-intercept?

What is the x-intercept?

What is the equation of the line?

The x-intercept is 0

The y-intercept is 0

Does this relationship represent a direct variation?

f(2)>f(-2)

f(-2)=

Yes, the relationship represents a direct variation. The k = -2

f(-2)=4 The point (-2,4)

False. f(-2)=4 and f(2)=-4 so f(-2)>f(2)

About angles...

• They are formed when two lines meet ata point (vertex).
• They are measured in degrees (°).
• They indicate the opening between the lines.
• They are fundamental in geometry and othermathematical areas.

Geometric figures...

• Square: A quadrilateral with 4 equal sides and 4 right angles.

• Pentagon: Five sides and five interior angles, and the total sum of the interior angles is 540 degrees.
• Hexagon: Six sides and six interior angles, and the sum of its interior angles is 720 degrees.

• Circle: A round figure where all points are at the same distance fromthe center.
• Triangle: A figure with three sides. Types: equilateral (all sides equal), isosceles (two sides equal), and scalene (all sides different).

• Rectangle: A quadrilateral with 4 right angles, but its opposite sides are of equal length.
