Answer:
y = -1/7x +5
Explanation:
It is convenient to start with the 2-point form of the equation of the line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (6 -7)/(-7-(-14))(x -(-14)) +7 . . . . . fill in the first two point values
y = -1/7(x +14) +7 . . . . . . . . . . . . . . . . simplify some; next finish simplifying
y = -1/7x +5
