=========================================
Problem 6a

The slope of line A is -1/1 or just -1
The reason why is because we start at (0,3) and move down 1 and over to the right 1 to get to the next point (1,2). Alternatively you can use the slope formula m = (y2-y1)/(x2-x1) to get the same result.

Since the slope of line A is -1, this means that we'll write "-1" in the first row of the "constant rate of change" column. 

-----------------------------------------
The two points (0,2) and (1,3) are on the line B

Use the slope formula to get

m = (y2-y1)/(x2-x1)
m = (3-2)/(1-0)
m = 1/1
m = 1

The slope of line B is 1. Write "1" in the second row of the "constant rate of change" column.
-----------------------------------------
The points (0,-4) and (1,-2) are on line C

Slope:
m = (y2-y1)/(x2-x1)
m = (-2-(-4))/(1-0)
m = (-2+4)/(1-0)
m = 2/1
m = 2

The slope of line C is 2, which is written in the last row of the "constant rate of change" column.
-----------------------------------------
Now onto the y intercept column. 

Line A crosses the y intercept at the point (0,3) or simply 3 on the y axis. So we'll have 3 in the first row.

Write 2 in the next row under the "3" to indicate that the y intercept of line B is 2. The black line B crosses the y axis at 2 on the vertical number line.

Similarly, the y intercept for line C is -4. This red line crosses the vertical y axis at -4

-----------------------------------------

Now onto the x intercept

The x intercept of line A is 3. This is where the blue line crosses the horizontal x axis.

The x intercept of line B is -2. This is where the black line crosses the horizontal x axis.

The x intercept of line C is 2. This is where the red line crosses the horizontal x axis.
=========================================
Problem 6b

Equation D: y = 2+x 
is the same as
y = x+2

The slope here is 1 (since y = x+2 is the same as y = 1x+2) and the y intercept is 2.

The fact that 
Slope = 1
and
y intercept = 2
means we have a match with line B

-----------------------------------------

The equation y = -4+2x is the same as y = 2x-4

Slope = 2
y intercept = -4
this matches with line C

-----------------------------------------

y = 3-x is the same as y = -x+3
which can be written as y = -1x+3

Slope = -1
y intercept = 3
This matches with line A

put like terms together.orremember that the 45 becomes negative when moved to the other side.orthe minuses cancel out.
