Answer: (-2,-4)
Step-by-step explanation:
To find the midpoint between two points we need to find the mean average between the x and the y .
Since we know the midpoint will have to represent the missing coordinates by the variables.
Solve for x to find the x coordinate by first multiplying both sides by -4.
-6 + x = -8 Add -6 to both sides
+6 +6
x = -2
The x coordinate of the B is -2 now we need to find the y coordinate.
Multiply both sides by 2
4 + y = 0 Subtract 4 from both sides
-4 -4
y = -4
The y coordinate is -4 so the coordinates will be (-2,-4)

Step-by-step explanation:
[logical equivalence]
[morgan laws]
if 
is true, then 
is true and 
is too.
with true, then 
is false [double denial]
In the first equivalence it follows that 
is true [identity law]
Then it can be concluded that

Answer:
The line crosses the y-axis at -2
Step-by-step explanation:
y = mx + b 'm is the slope and b is the y-intersect (the place where the graph comes across the y-axis.
y = mx + b; y = mx + b; b = -2.
Answer:
Step-by-step explanation:
Slope m = 1
Point (1;8)
x1 = 1 and y1 = 8
y - y1 = m(x - x1)
y - 8 = 1(x - 1)
y - 8 = x - 1
y = x - 1 + 8
y = x + 7
