Mr. Belong CFA Review 1

Front

What is a solution in the context of a system of equations?

Back

A solution is a set of values that satisfy all equations in the system. For example, (2,1) is a solution if it makes both equations true.

Front

What does a scatter plot showing no trend indicate?

Back

It indicates that there is no clear relationship between the variables being plotted.

Front

How do you translate a geometric figure on a coordinate plane?

Back

To translate a figure, you move it a certain distance in a specified direction. For example, moving 6 down and 3 left means subtracting 6 from the y-coordinate and 3 from the x-coordinate.

Front

What is the measure of an angle if it is equal to another angle that measures 115 degrees?

Back

The measure of the angle is also 115 degrees.

Front

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

Back

Front

What does a slope of -3 indicate about a line?

Back

A slope of -3 indicates that for every 1 unit increase in x, y decreases by 3 units, showing a downward trend.

Front

What is a y-intercept?

Back

Front

How can you determine if two angles are equal?

Back

Two angles are equal if their measures are the same, which can be shown through calculations or geometric properties.

Front

What does it mean for a system of equations to have no solutions?

Back

It means that the equations represent parallel lines that never intersect.

Front

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

Back

A positive slope indicates that as x increases, y also increases, showing an upward trend.
