Points of intersection

Maths

What are the equations of the lines in the graph?

Estimate the point of intersection for the lines in the graph.

Decrease the gradient or increase the y-intercept.

Decrease the gradient or the y-intercept.

Increase the gradient or decrease the y-intercept.

Increase the gradient or the y-intercept.

How would you change y = 4x - 2 in order to increase the x-ordinate of the point of intersection?

How would you change y = 4x - 2 in order to increase the y-ordinate of the point of intersection?

How would you change y = -x - 1 in order to decrease the x-ordinate of the point of intersection?

In y = 3x + 2, what does the 3 represent?

In y = 3x + 2, what does the 2 represent?

Which of the following coordinates lies on y = 2x - 4?

Which of the following coordinates lies on y = -3x + 1?

Because the y-intersects are too far apart.

Why will y = 3x - 5 and y = 3x + 1 NOT intersect?
