This document contains two parts describing linear equations. Part 1 defines the slope m as 1/3 and the point P as (0,7). It then derives the equation 3y - 21 = x from the slope-intercept form. Part 2 finds the slope m as 1/7 by calculating the rise over run between two points. It then isolates y and writes the equation in slope-intercept form as y = x/7 + 38/7.

1. PARTE 1
m = 1/3
P = ( 0 ; 7)
Y – 7 = 1/3 ( x – 0 )
3y -21 = x
3y – x – 21 = 0

2. PARTE 2
Hallamos la pendiente:
m = ( 6 -5 ) / (4 – (-3))
m = 1/7
1/7 = ( y – 5 ) / ( x – (-3))
7y – 35 = x +3
Y = (x +38) / 7
Y = x/7 + 38/7
