If the discriminant of an equation is positive is true of the equation?
If the discriminant of a quadratic equation is positive, it indicates that the equation has two distinct real roots. This means that the graph of the equation intersects the x-axis at two points. A positive discriminant also suggests that the solutions are not repeated and that the parabola opens either upward or downward, depending on the leading coefficient.
What is true of an equation if its discriminant is zero?
it has one real solution
What is true about a quadratic if the discriminant is negative?
There are two complex solutions.
If the discriminant of an equation is zero is true of the equation?
That its roots (solutions) are coincident.
What is true of the discriminant when the two real number solutions to a quadratic equation are rational numbers?
The discriminant must be a perfect square or a square of a rational number.
The title of a graph should be a short description of the data that will be displayed. true or false?
It is true.

What do you mean if a linear model underestimates?
In graph form, the linear equation lies below the true line or curve.
Is it true a straight diagonal line on a distance versus time graph indicates constant speed?
The answer is TRUE because it is a straight line as the graph shows below. http://www.batesville.k12.in.us/physics/apphynet/Measurement/Images/d_vs_t2_graph.gif

What has no true roots?
An equation with a discriminant that is less than zero. Note that in getting the discriminant, use the general form: ax²+bx+c=0 D=b²-4ac
