What is the slope-intercept form of a line?

Back

The slope-intercept form of a line is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is a quadratic equation?

Back

A quadratic equation is a polynomial equation of degree 2, typically in the form y = ax^2 + bx + c, where a, b, and c are constants.

Front

What does it mean for integers to be consecutive odd integers?

Back

Consecutive odd integers are integers that follow each other in the sequence of odd numbers, such as 1, 3, 5 or 7, 9, 11.

Front

How do you solve a system of equations?

Back

You can solve a system of equations using methods such as substitution, elimination, or graphing.

Front

What is the meaning of the inequality symbol '<='?

Back

The symbol '<=' means 'less than or equal to', indicating that the value on the left can be less than or equal to the value on the right.

Front

What is the formula for the sum of three consecutive odd integers?

Back

If the middle integer is x, the sum is (x-2) + x + (x+2) = 3x.

Front

How do you represent a word problem as a system of equations?

Back

Identify the variables, translate the relationships and conditions into equations, and express them in a system.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

What does it mean for a graph to represent a solution to an inequality?

Back

A graph representing a solution to an inequality shows all the points that satisfy the inequality condition.
