Answer:
The correct statements are as follows;
1. They have different y-intercepts 
2. The substitution method results in false statement 8 = -1
3. There is no solution 
Step-by-step explanation:
Here, we want to select the statement that best describes the equations 
The equation for a straight line is generally;
y = mx + b
m is slope and b is the y-intercept 
slope of both is same ; 4
So first assertion is wrong 
they have different y-intercepts 
First y-intercept is 8, second is -1 
This is correct 
The third statement is correct too
if we equated both y;
4x + 8 = 4x -1 
We shall have 4x canceled out and left with 8 = -1 
(8,-1) is not a solution 
There is no solution is correct because after substituting, we have 8 = -1 which is not correct and also impossible
