Question

X- -14,-7,7,14
y-7,6,4,3
what is the equation of the line in slope intercept form

Answer 1

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
