Graphs and Coordinates Flashcards
How do we find the midpoint on a graph?
How do we find the gradient of a graph?
dy/dx
How do we know if two gradients are perpendicular?
They multiply to get -1
What is the equation of a line?
What is the discriminant?
What does it mean when the discriminant is > 0?
The graph has 2 real roots
What does it mean when the discriminant is = 0?
The graph has 1 real root
What does it mean when the discriminant is < 0?
The graph has no real roots
