What is the slope-intercept form of a linear equation?

Back

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

Front

How do you find the slope between two points?

Back

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

Front

What does a negative slope indicate about a graph?

Back

A negative slope indicates that as x increases, y decreases, showing an inverse relationship.

Front

What is the y-intercept in the equation y = -2/3x + 5?

Back

The y-intercept is 5, which is the value of y when x = 0.

Front

What does it mean for a graph to have a positive association?

Back

A positive association means that as one variable increases, the other variable also increases.

Front

What is the solution to the equation 4m + 2 = -3m + 16?

Back

The solution is m = 2.

Front

How do you determine the greatest value among scientific notations?

Back

Compare the exponents first; the one with the highest exponent is the greatest.

Front

What is the value of 5.0 x 10^8 in standard form?

Back

The value is 500,000,000.

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What does the term 'association' refer to in statistics?

Back

Association refers to the relationship between two variables, indicating how one may change in relation to the other.
