What is the coefficient of x in the equation 4y 5-x?
5
Is a linear equation the same as a function?
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
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.
Why can't a coefficient of x and y in standard form of a linear equation cannot both be zero?
Standard form of a linear equation is represented as Ax + By = C If A and B are the coefficients of the x and y and they are both equal to zero then C would always be equal to 0 for any given x and y value. 0x + 0y = 0 Since the linear equation is an equation between two variables that gives a straight line when plotted on a graph, (0,0) is a point itself and wouldn't be able to form a line.
What linear equations are not functions?
Yes. Any linear equation of the form x = c (meaning that the coefficient of y is zero and that the graphed line is vertical) is not a function, as all points are verticaly above or below every other point. This is by definition a nonfunction.
How can you determine when a function is increasing or decreasing?
Assuming the function is linear, the direction of the function can be determined by the coefficient's sign:[y = mx + b]Where m is the coefficient of x, if m is negative, then the function is increasing. If m is positive, the function is decreasing (this relationship is rather complicated and requires advanced calculus to prove).
What is the slope of the line that has the equation y4x 2?
y = 4x + 2 It has a slope (gradient) or 4. The slope/gradient of a linear function is simply the number in front of the x when the equation is in the form y=mx+b. (the coefficient of x).
What is the quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is?
The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?
What is the coefficient of x in the equation 4y 5-x?

Do a linear equation and a function share the same definition?
No. A function need not be linear. For example, y = sin(x) is a function of x but it is not a linear equation.
Is a linear equation the same as a function?
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
How do you draw a continuous linear decreasing function?
A continuous linear decreasing function is a line that goes on forever and has a negative slope (is downhill from left to right). For example, the line y = -x is a continuous linear decreasing function.
What are quadratic equations?

How can the degree of the equation tell us if the equation is linear or not?
A linear equation always has a degree of one because the slope has to be constant to form a line. So, x + 7 is linear, 7 - x is linear, 4x - 3.7 is linear, but anything with x2 , etc. is not linear.
Why can't a coefficient of x and y in standard form of a linear equation cannot both be zero?
Standard form of a linear equation is represented as Ax + By = C If A and B are the coefficients of the x and y and they are both equal to zero then C would always be equal to 0 for any given x and y value. 0x + 0y = 0 Since the linear equation is an equation between two variables that gives a straight line when plotted on a graph, (0,0) is a point itself and wouldn't be able to form a line.
In the slope-intercept equation for a line the coefficient of the x-term gives the .?
The coefficient of the x term gives the gradient of the slope.
What is an example of a coefficient?
In the equation 4x + 2 = 10, the coefficient of x is 4. This coefficient represents the value that multiplies the variable x.
