10
Lecture 1610 Find the Slope of the line that passes through (2, 4) and (2, -5). Slope

11
Lecture 1611 Plot the points and verify the slope. 12 2 1 (2, 4) (2, -5)

12
Lecture 1612 Plot the points and verify the slope. 12 2 1 (2, -5) (2, 4)

13
Lecture 1613 Find the Slope of the line that passes through (4, -3) and (-2, -3). Slope

14
Lecture 1614 Plot the points and verify the slope is 0. 12 2 1 (4, -3) (-2, -3) -2

15
Lecture 1615 Plot the points and verify the slope is 0. 12 2 1 -2 (-2, -3) (4, -3)

16
Lecture 1616 Y=mx+b m b Y= m x + b m = slope; b = y-intercept

17
Lecture 1617 Y=mx+b m-3/4 b-5 Y= m x + b m = slope; b = y-intercept

18
Lecture 1618

19
Lecture 1619 24 4 2 -2 (0, -5) (4, -8)

20
Lecture 1620 Y=mx+b m b Y= m x + b m = slope; b = y-intercept

21
Lecture 1621 Y=mx+b m4 b5 Y= m x + b m = slope; b = y-intercept

22
Lecture 1622 y = 4x + 5

23
Lecture 1623 12 4 2 -2 -4 6 8 (1, 9) (0, 5) y = 4x + 5

24
Lecture 1624 y = 4x + 5

25
Lecture 1625 Solve for y in terms of x 3x + 2y = 6 2y = 6-3x Subtract 3x from both sides y = (6-3x)/2 Divide both sides by 2 Write in y = mx + b form

26
Lecture 1626 Y=mx+b m-3/2 b+3 Y= m x + b m = slope; b = y-intercept

27
Lecture 1627 3x + 2y = 6

28
Lecture 1628 12 2 1 (0, 3) (2, 0)
