1. F, G, and H Do not go through (0, -2) !
2-A)Which graph best represents the equation of the line that passes through the point (0, -2) and that has a slope of (1/3) ?
LET US EXAMINE J MORE CLOSELY! F G H
F, G, and H Do not go through (0, -2) !
J goes through (0, -2) and has a slope of (1/3)!
K goes through
(0, -2) , but has negative slope! J K
OBJECTIVE 2

2. 2-A)Which graph best represents the equation of the line that passes through the point (0, -2) and that has a slope of (1/3) ? J A B
TO FIND THE SLOPE, WE GO
FROM POINT A TO POINT B
AND NOTICE THE CHANGE
IN THE COORDINATES:
2 UNITS UP 1 = 3
6 UNITS RIGHT
SO, J HAS THE RIGHT
SLOPE, (1/3), AND GOES
THROUGH (0, -2).
OBJECTIVE 2

3. 2-B)Which graph represents the solution for which x + y 4?
TO ANSWER THIS QUESTION, WE NEED TO HAVE y BY ITSELF ON THE LEFT SIDE OF  . MOVE X TO THE RIGHT SIDE AND CHANGE ITS SIGN: y  4 - X
NOW, LET’S COMPARE OUR
GRAPH WITH THE ONES GIVEN.
NOW, WE GRAPH y = 4 - X AND PICK A POINT FROM ONE SIDE OF THE LINE TO TEST. IF THE POINT MAKES x + y 4 A TRUE STATEMENT, WE SHADE THE SIDE THE POINT WAS PICKED FROM; IF NOT, WE SHADE THE OPPOSITE SIDE:
TEST POINT
(1, 5)
THIS IS NOT A TRUE
STATEMENT, SO WE SHADE THE OPPOSITE SIDE
x + y 4
1 + 5 4
6 4
OBJECTIVE 2

4. THIS SIDE SHOULD BE SHADED
2-B)Which graph represents the solution for which x + y 4? F
WRONG GRAPH
RIGHT SHADING!
THIS
SIDE
SHOULD BE
SHADED
CORRECT GRAPH
WRONG SHADING! H
K HAS THE
CORRECT
GRAPH AND
SHADING!
WRONG GRAPH
WRONG SHADING! J
WRONG GRAPH
WRONG SHADING! G K
