1. Which line is the flattest (or is less steep)? Why?

y = 5x -6
y = 5x + 6
y = x - 3
y = x + 3
2. The line y = 4x - 7 crosses the y axis at:

(4, 0)
(0, 4)
(-7, 0)
(0, -7)
3. You are sliding a big cabinet down a truck ramp for a customer. You must maintain control of the cabinet because it is very heavy. There are 2 ramps in the building.

The equation of ramp 1 is y = 2x + 7 and the equation of ramp 2 is y = 3 x + 7. Which is the safest ramp to slide the cabinet down without losing control and why?

4. Write the equation of a line whose slope is 6 and whose y intercept is -3.

5. Find the x and y intercepts of each linear equation. Be sure to write your answers as ordered pairs.

y = 3x - 6
6y = -x + 2
6. What happens to the graph of the line y = 3x -2 when the equation is changed to y = 3x +6?

7. What happens to the graph of the line y = 2x - 5 when the equation is changed to y = 5x + 6?
