Chapter 6, Lesson 7

6-7.A identify the slope and y-intercept of a line from an equation
Which of these lines have a slope of 3 and a y-intercept of 2?
2y = 3x + 2
II y = 3x — 2
III y — 2 = 3x
(a) I and II only (b) I and III only (c) I only (d) III only

6-7.B graph an equation in slope-intercept form
Graph the line whose equation is .

6-7.C write an equation of a line using slope and y-intercept
Write, in standard form, the equation of the line whose slope = and whose y-intercept = 3.
