Moving a Point on the Coordinate Grid
Move around the point.
See how its and value change as its location changes.
Distance Between Two Points
Move Point A or B.
Notice how the distance between the two points changes.
Distance Between Two Points
The Slope-Intercept Form of a Linear Equation
The slope-intercept form of a linear equation is .
Move slider . See the steepness of the line change. The slope of the line is .
When is negative, the direction of the line changes. When , the line is flat.
Vertical lines do not have a slope.
Where the line intersects the -axis is the -intercept point of the line. The -intercept is the point .
Only the is used in the equation, and it is the constant term of the equation.
Move slider . See the line move up or down.
When is positive, the y-intercept is above the -axis.
When is negative, the y-intercept is below the -axis.
The Slope-Intercept Form of a Linear Equation
Equations of Parallel Lines
Line and Line are parallel lines. They have the same slope.
is the slope-intercept form of a linear equation.
The slope is .
Move slider . The slope for both lines will change.
Move slider . Line will move, but line will be stationary.
