Answer:y= -9x-25

Step-by-step explanation: Write the slope-intercept form of an equation of the line with slope -9 and passes through the point (-2, -7).

--------

Form:: y = mx + b

Solve for "b"::

-7 = -9*-2 + b

-7 = 18 + b

b = -25

-----

Equation:

y = -9x - 25

---------------

-----------

point slope formula

y-y1=m(x-x1)

y+7= -9(x+2). Notice that we are subtracting a negative, so we have to add.

 

y+7=-9x-18

y= -9x-25
