The equation y = 2x+1 represents a function is true.
A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. A linear equation is an algebraic equation of the form y = mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
For the given situation,
The equation is y=2x+1.
Here, x is the independent variable and
y is the dependent variable.
For different values of x, we can get different values of y.
Let us assume x = 0,
⇒ [tex]y=2(0)+1[/tex]
⇒ [tex]y=1[/tex]
For x = 2,
⇒ [tex]y=2(2)+1[/tex]
⇒ [tex]y=5[/tex]
Hence we can conclude that the equation y = 2x+1 represents a function is true.
