Chapter 2
1. What is the Cartesian coordinate system?
The Cartesian coordinate system is a coordinate system that uses Cartesian coordinates to locate points in a plane. It consists of a set of perpendicular lines called axes, with each line labelled with a number. The horizontal axis is labelled x and the vertical axis is labelled y. Points are then located by specifying their distance from the origin along each axis, measured in units of the chosen coordinate system.
2. What is a coordinate?
A coordinate is a number that specifies the location of a point on a plane. It is measured using a Cartesian coordinate system, which uses two perpendicular lines called axes. The horizontal axis is labelled x and the vertical axis is labelled y.
3. What is the distance between two points?
The distance between two points is the length of the straight line segment that connects them. It is measured in units of the chosen coordinate system.
4. What is the equation of a line?
The equation of a line is a mathematical formula that describes the relationship between the points on a line. It is written in the form y = mx + b, where m is the slope of the line and b is the y-intercept.
5. What is the slope of a line?
The slope of a line is a measure of its steepness. It is calculated by dividing the change in y-coordinates by the

1. Quadratic equation is an equation in which the highest power of the variable is 2.
2. Quadratic equation has the form ax2 + bx + c = 0, where a, b and c are real numbers.
3. The solutions to a quadratic equation are the values of x that make the equation true.
4. To solve a quadratic equation, we need to find the values of the coefficients a, b and c and then use the Quadratic Formula.
5. The Quadratic Formula is:
x = (-b ± √(b2 – 4ac))/2a
6. If the quadratic equation is in standard form, then the solutions can be found by using the Quadratic Formula.
7. If the quadratic equation is not in standard form, we can use the Quadratic Formula to put it in standard form.
8. The discriminant is a measure of the nature of the solutions to a quadratic equation.
9. If the discriminant is positive, then there are two distinct solutions.
10. If the discriminant is negative, then there is no real solution.
