Answer:

[tex]y +9 = -4(x - 4)[/tex]

Step-by-step explanation:

Given

[tex]m = -4[/tex] --- slope

[tex](x_1,y_1) = (4,-9)[/tex] --- point

See attachment for complete question

Required

Determine the line equation

This is calculated as follows:

[tex]y - y_1 = m(x - x_1)[/tex]

Substitute values for m, x1 and y1

[tex]y - (-9) = -4(x - 4)[/tex]

Simplify the expression on the left-hand side:

[tex]y +9 = -4(x - 4)[/tex]
