Y = -2x - 3

First make a table, then start inserting the x's you choose and figure out the y's.

x             y
----------------------
-2       -2(-2) -3
             4 - 3
                 1
-----------------------
-1        -2(-1) - 3
               2 - 3
                 -1
------------------------
0          -2(0) - 3
               0 - 3
                -3
-------------------------
1           -2(1) - 3
               -2 - 3
                 -5
--------------------------
2           -2(2) - 3
               -4 - 3
                  -7
--------------------------

Now you can plot the points into a graph.
(-2, 1), (-1, -1), (0, -3), (1, -5), (2, -7)

Sunny_sXe [5.5K]

Answer:

greater than

Step-by-step explanation:

Since 2 \frac{3}{8} is being multiplied by a number greater than 1, the result will be greater than 2 \frac{3}{8}

If the multiplier was 1 then the result would be equal to 2 \frac{3}{8}

If the multiplier was between 0 and 1 the result would be less than 2 \frac{3}{8}

1. Calculate slopes of n and m. N = -2 and M = -7/4. The two slopes aren't the same thus they are not parallel

2. Slope of m = -7/4 and k = 4/7. By definition of perpendicular these two fit the description. (to be perpendicular, k = -1/m
