Write the equation for the linear function that has the points (-2, 3) and (1, -6).

Question

Show all work please, I really don't understand this...

Answer 1

I suggest the point-slope form:

 

y - y₁ = m(x - x₁)

 

m = [3 - (-6)] / (-2 - 1) = -3

 

Pick either point.  Using the first one,

 

y₁ = 3

x₁ = -2

 

y - 3 = -3(x + 2)

 

You can change to standard form or slope-intercept form if you wish.
