Use the sliders to change the value of the x- and y- intercepts of the line. See if you can answer the equations below.[br]1. When x and y are both positive, does the line point up or down (from left to right)?[br]2. When x and y are both negative, does the line point up or down (from left to right)?[br]3. When y is positive and x is negative, does the line point up or down (from left to right)?[br]4. When y is negative and x is positive, does the line point up or down (from left to right)?[br]5. When x is large and y is small (but same sign), is the line steep or flat?[br]6. When y is large and x is small (but same sign), is the line steep or flat?[br]7. What kind of line do you get when the x-intercept is 0? [br]8. What kind of line do you get when the y-intercept is 0?
