Key Vocab:Standard Form of a line
Linear Function:
Solution of an equation in two variables: Is an ordered pair (x,y)
Graph of an equation in two variables: is the set of points in a coordinate plane that represents all solutions of the equation
Example 2, 3 and 4 Graph the functions by using a t-table

Lesson 4-3 Graphing using x and y intercepts pg.225
Key Vocab:x-intercept: Place where it intersects the x axis. (x, 0) y = 0
y-intercept: Place where it intersects the y-axis (0,y) x = 0
Example 1 find the x and y intercepts then graph COVER UP METHOD

Math 1 Date:________Lesson 4-5 Graphing using slope-intercept form to graph pg. 244
3 types of equations for linesStandard form Slope-intercept form point-slope form
Example 1 identify the slope and the y-intercept of the line with the given equation
Graph the equations if in standard form use the COVER UP method (two points), if in slope intercept form or if you can easily get y by itself. use the slope and the y-intercept (point slope)
2 points method a point and slope method a point and slope method
