What is the equation for the graph shown below?

Answer : The correct option is, (C)

Step-by-step explanation :

The general form for the formation of a linear equation is:

.............(1)

where,

x and y are the coordinates of x-axis and y-axis respectively.

m is slope of line.

First we have to calculate the slope of line.

Formula used :

Here,

and

Now put the value of slope in equation 1, we get the linear equation.

From the given options we conclude that the option C is an equation of the given line in standard form.

Hence, the correct option is, (C)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
