A city planner is rerouting traffic in order to work on a stretch of road. The equation of the path of the old route can be desc
Alborosie

Answer:

The correct option is;

y - P = two fifths (x - Q).

Step-by-step explanation:

The equation for the old route is given as follows;

y = \dfrac{2}{5} \cdot x - 4

Therefore, we have;

The slope of the equation of the old route = 2/5

Given that the new route is parallel to the old route and passes through the point (Q, P), the slope of the new route = 2/5 and the equation of the new route in slope and intercept form can be written as follows;

y - P = 2/5×(x - Q)

Therefore, the correct option is y - P = two fifths (x - Q).
