The equation of a linear function is y=2.5x-4
line with a slope of m passes through the point (x₁, y₁) is
y-y₁= m(x-x₁)
here x₁=4
y₁=6
m=5/2
line with a slope of 5/2 passes through the point (4, 6) is
y-6=5/2(x-4)
y-6=2.5x-10
y=2.5x-4
A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph. If the function has more variables, they should all be constants or known variables in order for the function to continue to work as a linear function.
A linear function is a function that, when plotted, creates a straight line. Typically, it is a polynomial function with a maximum degree of 1 or 0. Nevertheless, calculus and linear algebra are also used to express linear functions. The function notation is the sole distinction. It is also important to understand an ordered pair expressed in function notation. When an is an independent variable on which the function depends, the expression f(a) is referred to as a function.
