Answer:

Step-by-step explanation:
The first line has a slope of -5/3 found using the points in the slope formula.

Parallel lines have the same slope. So -5/3 is the slope of the second line. Write its equation using the point slope form  .

Answer:
Step-by-step explanation:
One solution:  when two lines intersect in exactly one point.
Infinitely many solutions:  When one of two lines can be shown algebraically to be exactly the same as the other.  The two lines coincide.
No solution:  The two lines have the same slope but different y -intercepts.  They can't and don't intersect.
 
        
             
        
        
        
Answer:
A. 7 years old
Step-by-step explanation:
6x-7=35 is the equation.
Add 7 to both sides, which gives you 6x=42.
Then both sides by 6, so 6/6=x and 42/6=7
So, x=7.
Since x is his daughter's age, x=7, so his daughter is 7.
