<p> Name: ______Test #3a -- Fall 1999 Beginning Algebra</p><p>Instructions: Show all necessary work. Box your final answer when appropriate. Attach your notecard to the back of the exam. Good luck!</p><p>1. Label the Rectangular Coordinate System with the following elements: a) origin (use the correct ordered pair) b) four quadrants c) the x & y axes d) up to positive and negative 5 on both axes (assume each line is 1 unit) e) the following ordered pairs: (-5,1) ; (3,-2) ; (2,3) ; (-1,-5) f) the two points shown on the axes with the correct ordered pairs</p><p>2. For the given linear equation complete the solution table. 2x + 3y = 5</p><p> x y -2 1 6 3. For the equation: -5 + 2y = 3x a) Put the equation in slope-intercept form</p><p> b) Give the y-intercept as an ordered pair</p><p> c) Give the x-intercept as an ordered pair</p><p> d) State the slope. m = </p><p>3. Give the slope of a horizontal line. ______</p><p>4. Give the equation of the line passing through the points (5,-1) and (-2, 15). Be sure to show your work for finding the slope, and then plugging into the point-slope form, before you give the final equation in slope-intercept form. 5. Circle the graph that would best represent the graph of the line: y = -x  1</p><p>6. What type of line has an undefined slope? ______</p><p>7. Graph the following linear inequality in two variables on your own graph paper. Don't forget to show your work for your three points to graph the line, for the check points. 2x  y  5</p><p>8. Give three ordered pairs that are solutions to the linear inequality in number 7. 9. Lines which are perpendicular have ______slope(s). (Fill in the blank with the most appropriate of the following.) a) different b) negative reciprocal c) the same</p><p>10. Write the equations of any two lines which are parallel to one another. Write them in slope-intercept form. A line is not considered parallel to itself.</p>
