3-4 Flashcard - Equations of Lines

Front

What is the slope-intercept form of a line?

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 identify the slope from the equation y = 1/2 x + 2?

Back

The slope is 1/2.

Front

What does the y-intercept represent in the equation of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form.

Front

Given the slope of 5, what is the equation of the line with a y-intercept of 0?

Back

The equation is y = 5x.
