y = -0.60x - 4
because the slope stays the same because it is parallel and the y intercept for the new equation ends up being -4
For a system of two variables and two equations, each equation will be a linear graph, and where the lines intersect is the solution as an ordered pair (x,y). If the lines don’t intersect (they’re parallel) so there is no unique solution.

Answer:
(3)
and 
(4) 
Step-by-step explanation:
Question 3
Required
Solve for x and y
We have:
--- angle on a straight line
Collect like terms


Solve for x


Also:
---- opposite angles
So, we have:



Divide by 2


Question 4:
Required
Solve for x
We have:
---- angle at right-angled
Collect like terms


Divide by 16
