Answer:
1/84 or 0.0123...
Step-by-step explanation:
Slope of line ST = Slope of line PQ = -3.
y = -3x + c
When x = 3, y = -1
=> (-1) = -3(3) + c, c = 8
Therefore the equation of line ST is y = -3x + 8 and the y-intercept is 8.
The y intercept only occurs when x=0 so (0,0) is the only y intercept of those choices.
