Pre-Assessment Coordinate Geometry Equations

What is the gradient-intercept form of a line?

Explain the concept of parallel lines in coordinate geometry.

• Parallel lines in coordinate geometry intersect at one point.

• Parallel lines in coordinate geometry have the same gradient.

• Parallel lines in coordinate geometry are always equidistant.

• Parallel lines in coordinate geometry have different gradient.

What is the condition for two lines to be perpendicular to each other?

• Two perpendicular lines have the same gradient.

• The sum of the gradients of two perpendicular lines is 1.

• Perpendicular lines intersect at a 90-degree angle.

• The product of the gradient of two perpendicular lines is -1.
