Rotation is a change in orientation without size change. There are six possible rotations: 90, 180, 270, 360 degrees. Clockwise rotations are negative, counterclockwise are positive. Direction doesn't matter for 180 and 360-degree rotations
Equation is rewritten as y=x² in vertex form. Vertex coordinates are (0,0). Parabola opens up since a=1
A coordinate plane is formed by two number lines intersecting at the origin. The horizontal axis (x) and vertical axis (y) intersect at (0,0). The plane contains four quadrants with different values on the axes. Each axis has a scale that increases in equal increments
Graphing functions involves plotting curves on coordinate planes. Every point on a curve must satisfy the corresponding function equation. Simple functions like linear and quadratic can be plotted easily
Slope measures the steepness and direction of a line in the coordinate plane. Slope is calculated as the ratio of vertical change to horizontal change. Slope formula: m = tan θ = (y2 - y1)/(x2 - x1)
The Cartesian plane is divided into four equal quadrants by the intersection of the x- and y-axes. The origin is located at (0,0) at the intersection of the axes. Points are plotted using ordered pairs (x,y) with coordinates indicating their position
