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

Back

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

How do you determine the slope from two points on a line?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

What does the slope of a line represent in a real-world context?

Back

The slope represents the rate of change between two variables. For example, in a financial context, it can represent the amount of money earned per hour worked.

What is the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x is 0. It represents the starting point of the line on the y-axis.

How can you write an equation in slope-intercept form from a word problem?

Back

Identify the slope and y-intercept from the context of the problem, then use the slope-intercept form y = mx + b to write the equation.

What is the significance of the slope in a real-world application?

Back

The slope indicates how one quantity changes in relation to another, such as speed, cost per item, or growth rate.

How do you identify a table of values that satisfies a linear equation?

Back

Substitute the x-values from the table into the equation and check if the resulting y-values match those in the table.

Front

What does it mean if a line has a slope of 0?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes; the output remains constant.

What is the formula for calculating the rate of change?

Back

The rate of change can be calculated using the formula (change in y) / (change in x), which is equivalent to the slope of the line.
