Answer: y - 6 = -10 (x - 1)   OR   y = - 10 x + 16

Step-by-step explanation:

For us to write the equation for this line, we need to (1) find the slope of the line, and (2) use one of the points to write an equation:

The question gives us two points, (2,-4) & (1,6), from which we can find the slope and later the equation of the line.

Finding the Slope  

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)  

                                          =  (-4 - 6) ÷ (2 - 1)

                                         =  - 10  ÷  1

                                         =  - 10

 

Finding the Equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line; where (x₁ , y₁) = (1, 6):

                           ⇒  y - 6 = -10 (x - 1)

     we could also transform this into the slope-intercept form ( y = mx + c)

                    since y - 6 = -10 (x - 1)

                               y - 6 = -10 x - 10 (-1)

                             ⇒  y = - 10x + 16

To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.
