What is the formula to find the value of Y in a linear equation?

Back

Y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the notation (-8,-4) represent in coordinate geometry?

Back

It represents a point in a Cartesian coordinate system, where -8 is the x-coordinate and -4 is the y-coordinate.

Front

What is the formula to find the value of X in a linear equation?

Back

X = (Y - b) / m, where m is the slope and b is the y-intercept.

Front

Define a linear equation.

Back

A linear equation is an equation of the first degree, meaning it has no variables raised to a power greater than one.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in Y over change in X).

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation Y = mx + b.

Front

How do you solve for Y in the equation 2Y + 3 = 13?

Back

Subtract 3 from both sides to get 2Y = 10, then divide by 2 to find Y = 5.

Front

What does it mean to find the coordinates of a point?

Back

Finding the coordinates of a point means determining its position in a Cartesian plane, represented as (x, y).

Front

What is the significance of parentheses in coordinate notation?

Back

Parentheses indicate that the values inside are coordinates of a point, distinguishing them from other mathematical expressions.

Front

How do you express a negative number in coordinate notation?

Back

A negative number is expressed with a '-' sign before the number, e.g., (-1, -2) indicates both coordinates are negative.
