Dear Medina,
 
We know two points on the line: (13, 9) and (30, 26).
 
We know that slope intercept form is y = mx + b
 
The slope, m, is given by (26 - 9)/ 30 - 13) = (17)/(17) = 1
 
y = x + b
 
All we have to do now is to figure out the y-intercept, b
 
b = y - x
 
b = 9 - 13 = -4
 
Note that we would get the same result if we had used
 
b = 26 - 30 = -4
 
So the equation of the line is y = x - 4
