3 and 4. answered below
5. The point of intersection is where two lines intersect.
Step-by-step explanation:
you have -x+2y=6. finding the slope is very easy, you just have to isolate y.
2y=6+x ---> y = 3+ x/2. The slope would be 1/2 for the first one. the y intercept would be 3.
To graph, there are different ways of doing it. You can do it by finding the y intercept and x intercept, by making a chart and finding plotting points, or you can do it graphing the y intercept and doing rise over run from there.

Answer:
So the Percentage Increase = 15 %
Step-by-step explanation:
Given:
Original price = $ 90.00
New Price = $103.50
To Find:
Percentage Increase = ?
Solution:
Percentage Increase 
%
Now In our Given Data
Difference in Value = New Value - Original Price
Putting in the values
Difference in Value = 103.50 - 90.00
= $13.50
Now we Know all the value and the formula is
Percentage Increase %
Putting in the values
Percentage Increase 
%
%
= 15%
which tells us that
Percentage Increase = 15 %
