The slope (gradient) of a speed v time graph is acceleration.

If the graph is a straight line, then the acceleration is constant. if the slope is 0 (ie the line is horizontal) then the acceleration is 0, and the object is moving with a constant speed (which can be 0, ie the object is stationary).

If the graph is "slanted" then depending upon which way the line is "slanted" the object is accelerating or decelerating (the steepness of the slope gives the rate of this).

So the object is moving with constant acceleration and either speeding up or slowing down - which, and by how much, depends upon the gradient of the graph.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
