Answer 1

Things to know

• Linear Equations

→ An equation that pairs of solutions draws a line on the plane.

• Graphical Method

→ An intersection of two graphs is a common solution.

Solution

(The 1st Attachment)

y=0 and y=-7 represent a pair of lines on the plane.

However, two lines are parallel. There is no point of intersection. So, no common solutions exist.

There is no solution for the pair of equations.

A fact about line

$y=ax+b$ represents a line on a plane.

To show is simple. Raise x-axis to $y=b$. Now, the line represents $y=ax$, which is proportional.

We can make infinitely many similar triangles with $y=ax$, so the line is a hypotenuse of a triangle, which is a line.

This also proves why the slope is constant in a line.

Answer 2

Answer:

Given :-

two pair of equation

y = 0

y = -7

Solution :-

At first know what is a linear Equation

A linear Equation is a equation that may have infinite Solution. There are two types of linear equation

• Linear equation in 1 variable
• Linear equation in 2 variable

Now,

We may note that the both point are existing in parallel line. So, we know that if 2 point occur in same line then no solution occur. Thus, no solution
