Faheem wants to write equations in the form y = mx + b for the lines passing through point P that are parallel and perpendicular to line t. First he finds the slopes of these 2 lines. What could he do next to find the y-intercepts?

Substitute the slope and the coordinates of point P in y = mx + b and then solve for b for each equation.

Step-by-step explanation:

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
