Chapter 6 Graphs

A linear graph is the graphical representation of a linear equation. A linear equation is an equation that can be written in the form: Ax + By = C, for some real numbers A, B, and C where A and B, are not 0. In this section, we learn about Linear graphs, coordinates, Lines Parallel to the Coordinate Axes, vertical lines, intersection, equation of line, y equals x, straight line graphs, coordinates negative.

You can plot a straight-line graph using just the gradient and intercept, you don’t have to work out a table of values. In this section, we learn about Plotting, equation of line, intersection, horizontal lines, gradient, find the gradient of a line through two points.

A rate of change tells us how fast something changes in a given time period. Your speed measures how fast your position changes over time. In this section, we learn about Distance Time Graphs, Velocity Time Graphs Calculate Distance, gradient, speed-time graph.

A linear graph is the graphical representation of a linear equation. A linear equation is an equation that can be written in the form: Ax + By = C, for some real numbers A, B, and C where A and B, are not 0. In this section, we learn about Scatter diagrams plot and use, scatter graph.

A line segment is a part of a straight line. In this section, we learn about midpoint of a line segment, midpoint, distance between 2 points, parallel lines, perpendicular lines.

A quadratic equation contains a term in x^2 but no higher power of x. The graph of a quadratic equation is a curved shape called a parabola. In this section, we learn about Introduction to Sketching Quadratic Equations, plot quadratic graphs, solve equations using graph.

A cubic function contains a term in x^3 but no higher power of x. It can also have terms in x^2 and x and number terms. A reciprocal function is in the form k/( x ) where k is a number. In this section, we learn about cubic graph, reciprocals.

A circle is a round-shaped figure that has no corners or edges. The equation of a circle with center (0,0) and radius r is x^2+y^2=r^2. In this section, we learn about circle, equation of a circle with center (0,0), the equation of a tangent to a circle.
