Answer:
The correct answer is:
and
are the equations that have no solution.
Step-by-step explanation:
First of all, let us have a look at the rules for a pair of lines, that have solution or no solution.
Let the equations be:
and
1. There exists exactly one solution:
2. There exists infinitely many solutions i.e. lines are identical.
3. There exists No solutions i.e. lines are parallel and will never intersect.
Now, let us have a look at the given pair of lines:
Option a)
The ratio:
Hence, the lines are identical, infinite solutions.
Option b)
The ratio:
Hence, exactly one solution.
Option c)
The ratio:
Hence, exactly one solution.
Option d)
The ratio:
Hence, There is no solution.
The correct answer is:
and
are the equations that have no solution.
The slope of the linear regression equation y = 61. 93x - 1. 79 is attached with the response.
<h3>What is linear regression?</h3>Linear regression is the most primary and generally used predictive research. Regression calculations are utilised to represent data and to describe the association.
The slope of the linear regression equation represented in the graph is the straight-line cutting the intercepts on the y axis at 1.79.
