Question

Accepted Answer

### First Question:
# Brief Explanations:
The equation of a straight line is in linear form, so the form is linear equation.
# Answer:
linear equation

### Second Question:
# Brief Explanations:
A parabola is represented by a quadratic equation, so the form is quadratic equation.
# Answer:
quadratic equation

### Third Question:
# Brief Explanations:
The graph of a quadratic equation is a parabola, so the graphical representation is a parabola.
# Answer:
parabola

### Fourth Question:
# Brief Explanations:
The formula to solve quadratic equations $ax^{2}+bx + c = 0$ is $x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}$, which is the quadratic formula.
# Answer:
quadratic formula

### Fifth Question:
# Brief Explanations:
The highest (for downward - opening parabola) or lowest (for upward - opening parabola) point on a parabola is called the vertex.
# Answer:
vertex

### Sixth Question:
# Brief Explanations:
When two graphs intersect, the point of intersection is the solution to the system of equations (if the graphs represent equations), and it is called the point of intersection (or solution point).
# Answer:
point of intersection (or solution)

### Seventh Question:
# Brief Explanations:
The method of solving a system of equations by substituting one equation into another is called the substitution method.
# Answer:
substitution method

### Eighth Question:
# Brief Explanations:
A system of equations (or graphs) with no points of intersection has no solution (in the case of equations) or is inconsistent (in the case of a system of linear equations).
# Answer:
no solution (or inconsistent system)
