Graphs of Straight LinesHow to graph equations and find equations from graphs.
Tables of Values A table of values is used to generate points.These points can be plotted on the coordinate plane. A straight line drawn through these points creates the graph of the equation.
Example Graph y = 2x – 5 x 1 2 3 4 5 y -3 -1 1 3 5
Plot these points on the coordinate plane.x 1 2 3 4 5 y -3 -1
Draw a straight line through the points
Exercises Graph the following straight lines: y = 3x – 4 y = 2x + 1Look for a relationship between the graphs and their algebraic expressions!!!
The Gradient-Intercept Form of a Straight LineWhen a linear function is written in the form y = mx + b the m is its gradient and the b is its y-intercept.
What’s the Equation? For the following graphs, determine their equation.

The table and graph suggest another method of graphing a linear equation. This method is based on two numbers. The SLOPE This is the coefficient of x.
Laws of Exponents Whenever we have variables which contain exponents and have equal bases, we can do certain mathematical operations to them. Those operations.
