Question

(1,9);m=-13 this hard for me

Answer 1

Answer:

y - 9 = -13(x - 1)

Step-by-step explanation:

sounds as tho you want to find the equation of a line thru the point (1, 9) that has a slope of -13.  Use the point-slope formula y - k = m(x - h) for this purpose.  Here m = -13, h = 1 and k = 9.  Therefore,

y - k = m(x - h) becomes y - 9 = -13(x - 1).  This is the desired equation in point-slope form.
