Two lines that cross each other. Lines intersect at one point unless the lines fall directly on top of each other (in which case they are essentially the same line and are sometimes called coincidental).
Slopes and Angles of Elevation
: Determine the relationship between the slope of a line and the angle the line makes with a horizontal line.
: Examine the relationship between the coefficients in two linear functions if they are parallel, perpendicular, share the same intercept, and more.
Modifying the Slope and y-Intercept
: Examine the changes of a function as the slope and y-intercept of a linear function are modified.
Varied Slopes and Intercepts
: Discover what happens to a graph when you vary the values for m and b in the equation y = mx + b.
Math in Motion
: Explore the relationship of graphs and motion.
: Make a scale drawing of what a roof would look like.
Constructing Quadrilaterals 2
: Given various properties, determine whether a quadrilateral exists.
Constructing Quadrilaterals 3
: Given some quadrilaterals, construct other quadrilaterals with similar properties.
Forming a Square
: Find four equations whose graphs are oblique (slanted) lines that will intersect to form the vertices of a square.
Tangent Lines to a Circle
: How does a tangent line relate to the radius that intersects the tangent line?
