Front

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

Back

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

Front

How do you determine if a set of ordered pairs represents a function?

Back

A set of ordered pairs represents a function if each input (x-value) is associated with exactly one output (y-value).

Front

What does the slope of a line represent in a graph?

Back

The slope represents the rate of change of y with respect to x. It indicates how steep the line is.

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

How can you find the point where two linear equations intersect?

Back

To find the intersection point, solve the equations simultaneously to find the values of x and y that satisfy both equations.

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed. It can be written in the form y = mx + b.

Front

What is the meaning of the term 'function'?

Back

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

Front

How do you write an equation for a line given a slope and a point?

Back

Use the point-slope form: y - y1 = m(x - x1), where (x1, y1) is the point and m is the slope.

Front

What is the formula to calculate the total cost when making monthly payments?

Back

The total cost can be calculated using the formula t = pm + c, where p is the monthly payment, m is the number of payments, and c is the initial cost.

Front

What is the significance of the initial payment in a payment plan?

Back

The initial payment reduces the total amount owed and is often required before monthly payments begin.
