Step-by-step explanation:

(1):

Required: Solve for x and y

Make x the subject in

Substitute -3y - 14 for x in the first equation

Open bracket

Collect Like Terms

Divide both sides by -7

Substitute -4 for y in

Collect Like Terms

Divide by 2

Hence, the solution is:

(2):

-- points

--- slope

Required: Determine the line equation

This is calculated using:

This gives:
