Question

To graph an equation, type everything after “y =” into the space in the equations tab, then click graph on the right.

Graph the equation y = x. (type x in the “y1=” space).

1. What is the slope of this line?


2. Describe the graph (Is it a straight line? Does it slant upward or downward?).


Graph the equation y = – x (type – x in the “y2=” space).

3. What is the slope of this line?


4. Describe the graph (Is it a straight line? Does it slant upward or downward?).


5. Compare the lines for the equations y = x and y = – x. Describe how they are alike and how they ar

Answer 1

different (steepness, direction, etc.).


6. What can you conclude about positive and negative slopes?


Graph the equations y = 0.25x, y = 0.5x, y = 2x, and y = 5x in the online calculator.

7. Compare the lines for the equations. What do you notice about the steepness of the lines?


8. What can you conclude about how changing the slope in an equation affects its graph?



Graph the equation y = x.

9. Describe the y-intercept of this line.
Graph the equation y = x – 5.

10. Describe the y-intercept of this line. How did this line change from y = x?



Graph the equation y = x + 5.

11. Describe the y-intercept of this line. How did this line change from y = x?



12. What can you conclude about how changing the y-intercept in an equation affects its graph?
