FLASHCARD QUESTION

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x. It indicates how steep the line is and the direction it goes (positive or negative).

FLASHCARD QUESTION

Front

What is the y-intercept in a linear equation?

Back

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

FLASHCARD QUESTION

Front

How do you write a system of equations?

Back

A system of equations is written as two or more equations that share the same variables. For example: 2x + 3y = 6 and x - y = 2.

FLASHCARD QUESTION

Front

What is the solution to a system of equations?

Back

The solution to a system of equations is the point (or points) where the equations intersect on a graph, representing the values of the variables that satisfy all equations.

FLASHCARD QUESTION

Front

What is substitution in solving systems of equations?

Back

Substitution is a method where you solve one equation for one variable and then substitute that expression into the other equation.

FLASHCARD QUESTION

Front

What is elimination in solving systems of equations?

Back

Elimination is a method where you add or subtract equations to eliminate one variable, making it easier to solve for the other variable.
