Hi,

Identify the slope-intercept form of the equation of a line which contains the points 

(–2, –1) and 

( 3, 4)  m = -5/-5 = 1    |m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29

Using the standard slope-intercept form for an equation of a line y = mx + b 

 where m is the slope and b the y-intercept.  

  y = x+ b    |Using ordered pair (3,4) to solve for b

  4 = 3 +b

  1 = b     Line is y = x+1
