- Coordinate planes
- The plane formed by 2 number lines that intersect at their zero points dividing the plane into 4 quadrants
- Slope
- rise /run a ratio that measures a lines' steepness
- Parallel lines
- Lines in a plane that never intersect
- Function notation
- Replace the Y with f(x)
- X-intercept
- The X-coordinate at which a graph intercepts the x-axis
- Mapping
- The domain is pair with with an element in the range
- X-axis
- The horizontal line on a coordinate plane
- Standard form
- ax+by=c
- Point-slope form
- y-y1 = m(x-x1)
- Solution
- An order pair that make an equation true
- Perpendicular lines
- two lines that meet and form a right angle
- Rate of change
- A change in a quality over time (slope)
- Constant of variation
- what the k is in the equation y = kx
- Terms
