Answer:
Step-by-step explanation:
we know that
If the three points are collinear
then
we have
A (1, 2/3), B (x, -4/5), and C (-1/2, 4)
The formula to calculate the slope between two points is equal to
step 1
Find the slope AB
we have
substitute in the formula
step 2
Find the slope AC
we have
substitute in the formula
step 3
Equate the slopes
solve for x
simplify
