Unit 3- Practice Flashcard

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

What does the slope (m) represent in a linear equation?

Back

The slope (m) represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What does the y-intercept (b) represent in a linear equation?

Back

The y-intercept (b) is the point where the line crosses the y-axis, indicating the value of y when x = 0.

Front

Write the equation of a line with a slope of -1 and a y-intercept of -1.

Back

y = -x - 1

Front

If m = -7 and b = -8, what is the equation of the line?

Back

y = -7x - 8

Front

Back

The graph will have a slope of 2 and a y-intercept of 6.

Front

What is the equation of a vertical line at x = 2?

Back

The equation is x = 2.

Front

What is the equation of a horizontal line at y = -1?

Back

The equation is y = -1.

Front

Bob saves $40 per month. Write an equation for the total amount in his account after x months if he starts with $150.

Back

y = 40x + 150

Front

What is the meaning of the term 'linear equation'?

Back

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