Can you tell how a quadratic equation can become linear equation?
You can easily tell by substituting 0 for a.
What is the meaning of negative coefficient of x?
In the form y=mx+b, b is the y-intercept and m is the coefficient, so if an equation has a negative coefficient, m<0. As a graph, the slope of the line is negative.
How can you tell if an equation has at most one solution without solving it?
You can be certain if the equation is linear, that is, of the form ax + b = 0 where a and b are constants.
How can you tell how many solutions a quadratic equation will have without solving it?
A quadratic equation can have a maximum of 2 solutions. If the discriminant (b2-4ac) turns out to be less than 0, the equation will have no real roots. If the Discriminant is equal to 0, it will have equal roots. But, if the discriminant turns out to be more than 0,then the equation will have unequal and real roots.
How do you find the point-slope of an equation?
The question only makes sense if the equation is a linear one. You rearrange the terms of the equation so that you have y on one side of the equals sign and the rest on the other side. Divide through by the coefficient of y so you then have the equation in the form y = mx + c One point on the line is (0, c) and the slope is m.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is?
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
What is the coefficient of x in the equation of a graph that has slope 0?
y=mx has a slope of m, if the slope is 0, m must be 0. So the coefficient of x is 0.
In a mathmatical equation what is the coefficient?
A coefficient is a number or symbol in front of an algebraic term in an equation. Examples: 4x2 + 2xy - x, the coefficient of x2 is 4 , the coefficient of xy is 2, and the coefficient of x is -1. ax2 + bx + c = 0 where a, b, and c are coefficients that represent any number.
Why can't an equal 0 in a quadratic equation?
a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.

The vertex of this parabola is at -3 -1 When the y-value is 0 the x-value is 4 What is the coefficient of the squared term in the parabolas equation?
The vertex of this parabola is at -3 -1 When the y-value is 0 the x-value is 4. The coefficient of the squared term in the parabolas equation is 7
What are quadratic equations?
In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is : where a≠ 0. (For if a = 0, the equation becomes a linear equation.) The letters a, b, and c are called coefficients: the quadratic coefficient a is the coefficient of x2, the linear coefficient b is the coefficient of x, and c is the constant coefficient, also called the free term or constant term. Quadratic equations are called quadratic because quadratus is Latin for "square"; in the leading term the variable is squared. A quadratic equation with real or complex coefficients has two (not necessarily distinct) solutions, called roots, which may or may not be real, given by the quadratic formula: : where the symbol "±" indicates that both : and are solutions.
Choose the quadratic equation with a leading coefficient of 1 that has as solutions -4 and 7?
x^2-3x-28=0...................
What is the coefficient of the squared term in the parabola's equation when the vertex is at 2 -1 and the point 5 0 is on it?
A parabola with vertex (h, k) has equation of the form: y = a(x - h)² + k → vertex (k, h) = (2, -1), and a point on it is (5, 0) → 0 = a(5 - 2)² + -1 → 0 = a(3)² -1 → 1 = 9a → a = 1/9 → The coefficient of the x² term is 1/9
What does c stand for in the quadratic equation?
ax^2+bx+c, so it's the coefficient in front of your x^0 term
How do you know that a graph of a line is not a horizontal line?
The coefficient of x is 0 in the equation of line (The x term is missing).Equation of a horizontal line is of the type y=constant.For eg: y=3, y=-1 etc.
