What do we replace the point (2, -10) with in the linear equation y = mx + b?

Answer 1

(2,-10)

y=mx+b

-10=m(2) +b

-10 =2m +b

2m=-10-b

m =(-10-b)/2

or

b = -2m-10

without more information that's about all you can do with the point, solve for m or b.

if you had one more point on the line,

or knew the slope

or knew the y intercept, you could solve for the equation
