This is true. Parallel lines have the same slope, and therefore will not cross unless they are the same line. A 'solution' is the point where two or more lines cross through each other. When there is a system of parallel lines, there will be no solutions. If it is the same line, there will be an infinite number of solutions, technically.
Answer:
Option D is right
Step-by-step explanation:
It is correct .
Start by finding a common denominator.
In this case, it would be 21.
So, -12/21 + -28/21= -40/21
Answer:
y=-3x-2
Step-by-step explanation:
There is enough information to make a point-slope form equation that which we can convert into slope-intercept form.
Point-slope form is: 
We are given the slope of -3 and the point of (1,-5).
Convert into Slope-Intercept Form:
Answer:
y=650
Step-by-step explanation:
First add 25=y/(4+22) to get 25=y/26 then multiply both sides by 26 for y=650
