Graphs of Straight Lines How 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 x12345 y
Plot these points on the coordinate plane. x12345 y-3135
Draw a straight line through the points
Exercises Graph the following straight lines: 1.y = 3x – 4 2.y = 2x y = x – 5 4.y = -3x Look for a relationship between the graphs and their algebraic expressions!!!
The Gradient-Intercept Form of a Straight Line When a linear function is written in the form y = mx + b the m is its gradient and the b is its y-intercept.
Whats the Equation? For the following graphs, determine their equation.
