2. 2. #1 Graphing with a table by plugging in points.A ______________ always has a _______________ _______________ of _______________, or _______________.This means that all of the points on the line can connect with a _______________ ruler.One way we can graph is by making an X-Y Table. This is also known as an _______________ - _______________table or a _____ -_______________. 1. 2. x Plug In y Ordered Pair x Plug In y Ordered Pair -2 -2 -1 -1 0 0 1 1 2 2Chapter 5 SSS 2

Y-intercept (b) Slope Slope (m) Equation EquationSlope-intercept form is: y = ____x + b, where m = _______________ and (0, b) is the _______________.Remember, there are 4 types of lines:Uphill _______________, Downhill _______________, Horizontal _______________, and Vertical _____________.Chapter 5 SSS 6
7. 7. #4 Writing equations and graphing lines given a point and the slope.Use y = mx + b every time you write the equation of a Steps:line. Remember, m is the slope and b is the y-intercept.  First, identify m=____, x=____, and y=____.If you are given a point (x, y) and the slope, just plug in  Second, write out y = mx + b by plugging in thethe numbers and solve for b and say BYE! numbers, ____ = ____(____) + b.  Third, solve for b (Do/Undo).  Lastly, plug in m and b into the equation as final answer. 35. 36.  Identify m=_____, x=_____, y=_____.  Identify m=_____, x=_____, y=_____.  Plug in _____=_____(_____) + b.  Plug in _____=_____(_____) + b.  Solve for b:  Solve for b:  Plug in m and b, y = _____x + _____.  Plug in m and b, y = _____x + _____.

14. 14. #7 Finding x- and y-intercepts of a line in standard form.Standard Form of a Linear EquationThe standard form of a linear equation is , where A, B, and C are real numbers and A and B are notboth zero.Standard form is when _____ and _____ are on the __________ __________. To find the x-intercept, cover up the_____ term and solve for x. It will be an ordered pair (_____, 0). To find the y-intercept, cover up the _____ termand solve for y. It will be an ordered pair (0, _____). 59. 60. x-intercept: x-intercept: y-intercept: y-intercept: 61. 62. x-intercept: x-intercept: y-intercept: y-intercept: 63. 64. x-intercept: x-intercept: y-intercept: y-intercept: 65. 66. x-intercept: x-intercept: y-intercept: y-intercept: 67. 68. x-intercept: x-intercept: y-intercept: y-intercept: 69. 70. x-intercept: x-intercept: y-intercept: y-intercept: 71. 72. x-intercept: x-intercept: y-intercept: y-intercept: 73. 74. x-intercept: x-intercept: y-intercept: y-intercept:Chapter 5 SSS 14
