Given:
DE contains the points D(1, -2) and E(3, 4).
FG contains the points F(-1, 2) and G(4, 0).
To find:
Is DE perpendicular to FG.
Solution:
Slope of DE:

Here 


m = 3
Slope of FG:

Here 



<em>Two lines are perpendicular if product their slopes are -1.</em>
Slope of DE × Slope of FG


≠ -1
The solution is no, because the product of the slopes is not -1.

Answer:
x = 30
Step-by-step explanation:
In order for the lines to be parallel,
2x + 20 = 80
2x = 60
x = 30
Answer:
Step-by-step explanation:
For the first question the answer is 50(0.2 + 1)^2 = 72
For the second question it is y = 32
Step-by-step explanation:
In case you need to see how i got it...it's below
For number 1, y is proportional to (x + 1)^2
The equation would be y(x +1)^2 = k(the constant). Then I substituted numbers you gave me in the equation which was : 50(0.2 + 1)^2 = k(72)
For number 2 I used this equation: y (x + 1)^2 = 72. I substituted x for 0.5. The equation will be: y(0.5 + 1)^2 = 72. Then I got 32 for y.
