1 SB 149 IGC ALGEBRA I Adapted from Houston ISD Curriculum EOC Project: Create Your Own City Map As a city planner, you have been asked to create a street-map and master plan for a new sub-division that is being developed. Your final product must be represented on a coordinate plane and include all of the guidelines and requirements listed below. Project guidelines: All streets must be labeled with the name of the road. Buildings and landmarks must be labeled. Lines cannot be horizontal or vertical unless otherwise denoted. Each of the following community requirements must be represented by a different equation. For instance, you may not use the same equation to satisfy two different requirements. The map should be easy to read and colorful be creative! Community Requirements: 1. Locate and plot the City Central Square at the origin. 2. Draw a street that models the parent linear function and place your house at point (3,3). 3. Create one street modeled by a line with a positive slope passing through the points (-8,0) and (0,6). Write the correct equation for the line in function notation. Indicate the Domain and Range in set notation for the street. 4. Create one street modeled by a line with a negative slope passing through the points (0,-2), and (-7,0). Write the correct equation for the line in standard notation. Create a billboard that shows the table that corresponds to this linear equation (contains at least 4 points). 5. Create one street modeled by a line with a slope of 0 and has a y-intercept of -12 and a Domain of (-,10]. Write the correct equation for the line. Indicate the range for the street. 6. Create one street modeled by a line with an undefined slope that intersects your house and has a Range of [-1,6]. Write the correct equation for the line. Indicate the domain for the street. 7. Plot the location of the following public service buildings: Police station located at (-8,8), Fire station located at (-10,2), and the Hospital located at (-2,11). Calculate the slope between the Police Station and Hospital using only the slope formula. 8. Create a street that is parallel to the line from #4 that has a y-intercept of -6. Write the equation for the new street in slope-intercept form. 9. Create a u-turn street in your city modeled by a quadratic equation with the following conditions: a vertex at (3,6), a y-intercept of 10.5 and an a value of!. Write the function that models this u-turn in! vertex form and find the Line of Symmetry. 10. Create a park in your city by shading the region bounded by the equations from #2, #3, #4 and #8. Using the equations for those lines, correctly determine the inequalities that define the shaded region. 11. Create a hike and bike trail that models the following quadratic function: y = 2x! -16x -23 with a Domain of [-7, -1]. Place restroom facilities and a water fountain at the roots of the trail s function. Place a bench at the vertex of the trail s function. 12. Plot points to represent ten different businesses with a negative correlation in Quadrant IV. 13. Use substitution to find the intersection of the lines from #2 and #4. Page 1 of 3

2 14. Find the Exponential equation that passes through the following points: (-1,!! ), (0,1), (1,2), (2,4), (3,5). Indicate the Domain and Range in set notation for the street. 15. The population of your city in 1990 was 400,000 and is growing at a rate of 5% per year. Answer the questions on your city key using this information. Page 2 of 3
