Assignment – Straight line

WRAP UP AND ASSESSMENT

The gradients of a straight line is given as gradient = change in y / change in x.

The gradient of a curve at a point is given by the gradient of the tangent at that point.

The gradient at a turning point of any quadratic equation equals zero.

Exercise 14.5 no 1; the figure below (the text recommended) represents the graph of the function y = x2 + 4x – 5, (a) use the given tangents to find the gradient of the curve at (i) A (ii) B.

(b)        Use the Graph to find the roots of the function.

(c)        State the equation of the line of symmetry of the curve.
