2,4 and 8,13 slope

Answer 1

Hello Andrew,

My sincere apologies for the delayed response. I had been offline for a few. 

To determine the slope of a line given two pairs of coordinates, this is what you need remember: 

The slope of the line through (x_1. y₁₎ and (x₂,y₂) where x₁ ≠ x₂  is:

                                             y₂ - y_{1
                                                      ---------}
                                                       x_{2 -} x₁


Therefore: 

13 - 4
-------
  8 - 2

9/6 = Slope 


Do you need this as equation in slope-form? 

y - y₁  = m(x - x₁)  <-------Do you know how we arrive at this equation? 

y - 4 = (3/2)(x - 2)  <-------This is the equation in point-slope form. 

Simplify the equation to solve for y. 

Please let me know if this helped you and I wish you a great day tomorrow.
