CHAPTER 8
Section 8-1 – 8-5
INTRODUCTION TO FUNCTIONS
GRADS
I. Major Topics
1. Solve equations in two variables, given the domain
2. Graph linear equations
3. Use Standard form of the line and slope-intercept form of the line to determine slope and
and y intercept of the line and graph the line.
II. Objectives
By the end of this unit students will be able to
1. solve equations in two variables over given domains of the variables
2. graph ordered pairs
3. graph linear equations
4. find the slope and y intercept, given the equation of a line
5. find the equation of a line, given the slope and y intercept
6. determine the slope and y intercept of a line, given two points that satisfy the
equation of the line.
7. given two lines that are parallel, the equation of one of the lines and a point on the other
line, find the equation of the second line.
8. given two lines that are perpendicular, the equation of one of the lines and a point on the
other line, find the equation of the second line.
9. find the equation of the line, given the slope and one point on the line, or two points on the
line.
III. Vocabulary
By the end of this unit the student should be able to define the following math terms:
Ordered Pair, domain, range, abscissa, ordinate, plotting points, horizontal axis, vertical axis,
quadrant, origin, coordinate plane, Cartesian Plane, linear equation, standard form of the line –
Ax+By = C, slope, slope-intercept form of the line – y=mx + b, rise/run, perpendicular, parallel,
intercept
