What is the equation of a line in slope-intercept form?

Back

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

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What are the zeros of a function?

Back

The zeros of a function are the x-values where the function equals zero (f(x) = 0).

Front

What does it mean for a function to have a minimum value?

Back

A minimum value is the lowest point on the graph of the function.

Front

What is the difference between a linear equation and a quadratic equation?

Back

A linear equation has a degree of 1 (e.g., y = mx + b), while a quadratic equation has a degree of 2 (e.g., y = ax^2 + bx + c).

Front

How do you solve a linear equation?

Back

Isolate the variable on one side of the equation using inverse operations.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

How do you determine if a point is a solution to an equation?

Back

Substitute the x and y values of the point into the equation; if it holds true, it is a solution.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness and direction of the line (positive slope = rising, negative slope = falling).
