Y= -2x-9 in standard form

y= -2x-9 is in standard form itself with slope m = -2 and y intercept c as -9.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let, consider the equation of y = mx+c,

where, m is the slope of line and c is the y - intercepts. So to draw the graph firstly we find the two points to connect the line in which first is y-intercepts by putting x=0 in the given equation.

standard form of linear equation is :

y = mx+c  

comparing it with given equation :

y= -2x-9.

m = -2, c = -9

Therefore, y= -2x-9 is in standard form itself with slope m = -2 and y intercept c as -9.

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

2x +  y = -9.
