FLASHCARD QUESTION
Front
What is the y-intercept of a line?
Back
The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the slope-intercept form.

FLASHCARD QUESTION
Front
How do you write the equation of 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.
