Answer:
The two lines intersect (in other words, they have a common meeting points)
Step-by-step explanation:
Thinking process:
A linear equation takes the form of 
where , m = gradient
c = y-intercept (point where the line cuts the y-axis)\
Suppose we have these two linear equations: 
We can find the point of intersection by solving the two equations simultaneously like this:
sub y = 2x + 4 into equation (2) gives:
2(2x+4) = -6x -1
solving yields
- 0.9
Substituting x= -0.9 into equation 1 yields:

y = 2.2
In terms of the Cartesian coordinates (x, y) the point of intersection will be (-0.9, 2.2)
Hence, the point of intersection is a solution of two linear equations.
R = l + (3w)/2
Subtract 'l' to both sides:
r - l = (3w)/2
Multiply 2 to both sides:
2r - 2l = 3w
Divide 3 to both sides:
w = (2r - 2l)/3
Answer:
-88
Step-by-step explanation:
-a² + 4ab - b²
Substitute the variables with the numbers given.
-2² + 4(2×-6) - -6²
-2² + 4(-12) - -6²
-4 + 4(-12) - 36
-4 + -48 - 36
-52 - 36 =
-88
