Answer:
<em>B</em>
Step-by-step explanation:
<em>You know that the graph intercepts at the point of (4,-2)</em>
<em />
<em>Where x = 4 and y = -2.</em>
<em />
<em>This means that whenever you plug a value of x in the equation it should give the value of y.</em>
<em />
<em>For example when you plug x= 4 into the equation (B), it should look like this.</em>
<em />
<em>4- y = 6, solving for y gives us the value negative 2.</em>
<em />
<em>This means that it does give us this point, however, as the graph shows us, both lines meet at the point which means that both equation should give us this point.</em>
<em />
<em>If we substitute x = 4 in the second equation of b, we should be able to get 3(4) + 4y = 4. Solving for y gives us -2.</em>
<em />

Answer:
There are two possible values: MN=5 or MN=19
Step-by-step explanation:
The points L and N are collinear, so we can visualize them on a right line as in Figure 1.
First suppose that M is between L and N as in Figure 2. Then we can compute the distance between L and N as LN=LM+MN. Substracting LM from both sides, we obtain that MN=LN-LM=12-7=5.
For the other possibility, suppose that M is not between L and N as in Figure 3. Because LM<LN, it's impossible that M is located further to the right than N. Then M isn't at the right of L. Therefore, M is at the left of L, so L is between M and N, so the distance between M and N is given by MN=ML+LN=LM+LN=7+12=19.
