Your statement is correct.
y=mx+b when m is the slope and b is the y-intercept.
True
The coefficient of the x term gives the gradient of the slope.
The equation of the line is of the form y = 3x + c where c is a constant. The point (4,9) is on the line, so substituting x=4, y=9 in the equation, 9 = 3*4 + c = 12 + c so c = -3 So the equation of the line is y = 3x - 3
x
A coefficient is a number that accompanies a variable. For example, in the expression 2x + 4, the coefficient is 2.
A coefficient is the number before the variable (e.g. the 3 in 3x, or the 22 in 22x^2). For example, in the following quadratic equation, the coefficient to x is 4, and the coefficient to y is 12. 4x^2+12y+4 Remember that a number preceded by a ^ is a power, i.e 4x^2 is 4x squared.
y = 2x + 1.
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
The correct set of coefficient for an equation depends with the equation in question. There are many types of equations.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
Depends on the equation.
By itself there is none. A coefficient is the multiplying factor in a polynomial equation.
4K + O2 = 2K2O so the "coefficient" is 1
The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?
It depends on the equation.
There is no single coefficient for that equation, as a coefficient is the number by which any term is multiplied. The coefficients in that equation are 5, 2, 4 and 3.
The strength of the linear relationship between the two variables in the regression equation is the correlation coefficient, r, and is always a value between -1 and 1, inclusive. The regression coefficient is the slope of the line of the regression equation.
The coefficient in an expression is the multiplier of the variable in the equation. Here, the coefficient would be 6.
