When you are given the slope and the y intercept of a line, what formula should you use? - Answer: Slope intercept form If you are given two points, how do you find the slope? - Answer: change in ys over change in xs
How do the slopes of parallel lines relate to each other? - Answer: they have the same slope What is the formula for slope-intercept form? - Answer: y = mx + b What's the first step if you are given two points on the line and neither of them is the y-intercept? - Answer: find slope What does "m" represent? - Answer: Slope What does "b" represent? - Answer: The y-intercept When a line on a graph is vertical, is it intercepting the y or the x axis? - Answer: It is intercepting the x axis. When slope and one point are given, what form should be used to write the equation? - Answer: Point slope form How would you write the equation of a line given a graph in slope intercept form? - Answer: Find the y-intercept, as b, and then determine the slope, as m.
When a line on a graph is horizontal, is it intercepting the y or the x axis? - Answer: It's intercepting the y axis.
