Linear Function A linear function is a function whose graph is a straight line. The equation of a linear function of x can be written in the form f(x) = mx + b or a linear equation y = mx + b where m is the slope and b is the y-intercept. The equation in the form Ax + By = C where A‚ B and C are real numbers is referred to as the general form of a linear equation. We can rewrite a given linear equation Ax + By = C in the form y = mx + b and vice-versa using the basic properties of real numbers

accurate fit‚ I would propose creating a system of equations. Before jumping to far ahead‚ we need to make it clear the equation we are going to be analyzing. We will use the equation given to us by the polynomial trend line which is: y= ax2 + bx +c and the reason that we are using this equation is because of the fact that the R2 value is 0.9955. The closer the R2 value is to 1 the better it will fit the graph. We will rearrange the equation y= ax2 + bx +c so that we can solve for the unknowns

Physics E=mc2 The film starts out by describing how the equation E=mc² came about explaining each variable and the scientist’s whose ideas helped develop E=mc². In the movie E as in energy was explained first. Before energy’s discovery people thought that it was a composition of random forces acting upon someone or something that created movement. Michael Faraday went from being a blacksmith and became a scientist after being inspired after attending a speech from his idol Sir Humphrey Davy

reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD Equation 1 Equation 2 below will give the equilibrium constant‚ Keq‚ for this general reaction‚ where the square brackets refer to the molar concentration of the reactants and products at equilibrium.

of a line and one point on it. In order to solve a problem and write an equation using the point-slope form you need two things. Those things are a point on the line‚ (x‚y)‚ and the slope of the line. For example‚ say the slope of your line is 4 and a point on the line is (1‚5). You would insert the 4 in place of the m‚ the 1 in place of the x1‚ and the 5 in place of the y1. When you plug everything into the point-slope equation you get: y-5=4(x-1). The second form‚ slope-intercept‚ is written as
