Graphing Lines (1.2.2)

Question 1

• A graph is a way of illustrating a set of ordered pairs. One of the easiest objects to graph is the line. Lines have direction, but no thickness.

Question 2

• The slope-intercept form, y = mx + b, and the point-slope form, (y – y1) = m(x – x1), are two means of describing lines.

Answer 2

• The slope-intercept form, y = mx + b, and the point-slope form, (y – y1) = m(x – x1), are two means of describing lines.

Question 3

• When writing the equation of a line, the point-slope form is easier to use than the slope-intercept form because you can use any point.

Answer 3
