slope intercept form slider

How does changing the value of m (the slope) change the graph?

• The slope m has no effect on the graph.
• Changing m only affects the y-intercept of the line.
• The slope m determines the color of the line.
• The slope m determines the steepness and direction of the line; positive m slopes up, negative m slopes down.

How does changing the value of b (the y-intercept) change the graph?

• The graph rotates around the origin.
• The graph becomes steeper as b increases.
• The graph reflects across the x-axis.
• The graph shifts vertically (up/down) without changing its slope.

Which direction does the point move when you change the x₁ slider?

• The point moves horizontally

• The point moves diagonally.
• The point moves up or down.
• The point stays in the same position.

Which direction does the point move when you change the y₁ slider?

• The point moves horizontally.
• The point moves vertically.
• The point moves diagonally.
• The point remains stationary.
