What is the constant of proportionality in a proportional relationship?

Back

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise over run).

Front

How do you write a linear equation in the form y=mx+b?

Back

In the equation y=mx+b, m represents the slope and b represents the y-intercept, which is the value of y when x=0.

Front

What does the term 'linear equation' mean?

Back

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

Front

What is 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.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

Front

What is a solution to a linear equation?

Back

A solution to a linear equation is a pair of values (x, y) that makes the equation true when substituted into it.

Front

What does it mean for two quantities to be proportional?

Back

Two quantities are proportional if they maintain a constant ratio to each other, meaning as one quantity changes, the other changes at a consistent rate.

Front

How can you determine if a point is a solution to an equation?

Back

To determine if a point is a solution, substitute the x and y values of the point into the equation and check if the equation holds true.

Front

What is the significance of the constant of proportionality in a table of values?

Back

The constant of proportionality in a table of values indicates the consistent ratio between the dependent and independent variables.
