Linear Function Formula
A linear function is a polynomial function whose graph gives a straight line. The linear function formula is of the form.
Here x is independent variable, Y is dependent variable, m is slope and c is intercept.
Suppose the equation of line passes through the points (x1,y1) and (x2,y2) in a graph then the linear function is given by
Then the slope m is given by
Question 1: Solve: 3x + 5 = 0
Given function is 3x + 5 = 0
3x + 5 = 0
3x = -5
