Front

What is the result of subtracting matrix B from matrix A if A = [[1, 2], [3, 4]] and B = [[4, 3], [2, 1]]?

Back

The result is A - B = [[1-4, 2-3], [3-2, 4-1]] = [[-3, -1], [1, 3]].

What does the term 'slope' refer to in a linear equation?

Back

The slope indicates the steepness of the line and is calculated as the change in y over the change in x (rise/run).

Front

What is the definition of a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input from its domain.

Front

How do you determine if a set of points forms a linear function?

Back

A set of points forms a linear function if they can be plotted on a graph and all lie on a straight line.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation Y = mx + b.
