Which is an equation of the given line in standard form?
a.
–8x + 9y = 23
b.
–8x + 9y = –23
c.
–8x + 7y = 25
d.
–9x + 8y = –23

Answer : The correct option is, (A) -8x + 9y = 23

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 A is an equation of the given line in standard form.

Hence, the correct option is, (A) -8x + 9y = 23
