Answer:
-5/2
2/3
0
Step-by-step explanation:
Make a triangle with two points on the line.
Count the squares to get rise (change in y) and run (change in x).
Slope=rise/run
For (3), pick two easy points on the line. For example, (-1,2) and (-3,7).
Slope=(y1-y2)/(x1-x2)
Point1 = (-1,2): y1=2 and x1=-1
Point2=(-3,-7)): y2=7 and x2=-3
Slope=
=-5/2
Same process for others. Slope is about incline (think driving up a hill), so for (5) the slope is 0 because the line is horizontal.

Step-by-step explanation:
All the variables on the right are being multiplied together then the whole mess is being divided by 2. Let's get rid of the 2 first. The undoing of division is multiplication, so we will begin by multiplying both sides by 2 to get
Next we will move the m. The undoing of multiplication is division. So we divide both sides by m to get
The undoing of a square is to take the square root, so we will do that to both sides giving us, finally
