Midterm Review Part 2

Front

What is the Standard Form of a linear equation?

Back

The Standard Form of a linear equation is written as ax + by = c, where a, b, and c are integers, and a and b are not both zero.

Front

How do you write the equation of a line in Point-Slope Form?

Back

The Point-Slope Form of a line is written as y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

What does it mean when data shows a Strong Correlation?

Back

Strong Correlation means that the data points closely resemble a straight line, indicating a strong relationship between the two variables.

Front

What is the equation of a line that is parallel to the x-axis?

Back

The equation of a line parallel to the x-axis is of the form y = k, where k is a constant.

Front

What is the result of multiplying (-2√7)(3√28)?

Back

The result is -84.

Front

What is the Slope-Intercept Form of a linear equation?

Back

The Slope-Intercept Form is written as y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean when there is No Correlation between two variables?

Back

No Correlation means that there is no apparent relationship between the two variables; the data points do not follow any trend.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts.

Front

What is the formula for finding the slope (m) between two points (x1, y1) and (x2, y2)?

Back

The formula for slope is m = (y2 - y1) / (x2 - x1).

Front

What is the Double Intercept Form of a linear equation?

Back

The Double Intercept Form is written as x/a + y/b = 1, where a is the x-intercept and b is the y-intercept.
