y+9=-4(x-4)

Step-by-step explanation:

Linear equations can take various forms, such as:

Point–slope formTwo-point formSlope–intercept formIntercept formStandard form

The point-slope form of a linear equation is written as:

y-y_1=m(x-x_1)

Where:

$m=Slope\\x_1,y_1=Coordinates\hspace{3}of\hspace{3} any\hspace{3} point\hspace{3} of \hspace{3}the\hspace{3} line$

So, according to the data provided:

$m=-4\\x_1=4\\y_1=-9$

Replacing the data into the point-slope equation:

$y-y_1=m(x-x_1)\\\\y-(-9)=-4(x-4)\\\\y+9=-4(x-4)$

Therefore, the equation for the graph shown is:

y+9=-4(x-4)
