slope -3 through (2, -10)

Question

slope -3 through (2, -10)

Answer 1

I assume you seek the equation of a line of slope -3 that passes through (2,-10).

 

Start with 

 

y = mx + b

 

m = -3 (given)

 

y = -3x + b

 

Use the coordinates of the given point to find b.

 

-10 = -3(2) + b

 

b = -10 + 6 = -4

 

y = -3x - 4
