M=-2

and containing

with a slope

p (7,3)

What are you asking for?

Step-by-step explanation:

I can't get your question, but if you are asking for the equation of a line with the coordinates (7,3) and gradient m = - 2

we use the expression

y-y1 = m (x-x1)

substitute the y1 and x1 coordinates and gradient in the formula

y - 3 = - 2 (x-7)

y-2 = - 2x + 14

y=-2x+14+2

y=-2x+16

rearranging

2x+y-16=0

therefore the equation of that line is

2x + y - 16 = 0
