Parallel have same slope
Perpendicular have opposite reciprocal slopes. Ex. 2/3 is slope of one line so the perpendicular line would have slope of -3/2.
Find slopes of these lines.
-4x-5y=-4
-4x+4 =5y
Divide by 5
Y= -4x/5 +4/5
Second line: 10x-8y=-1
10x+1=8y
Divide by 8
10x/8 +1/8 =y
Y= 5x/4 +1/8
So if you look at slope of line 1= -4/5 and line 2 it’s 5/4 so these both are perpendicular.
Answer:
15 gallons of paint
Step-by-step explanation:
5 x 3 = 15
equal groups !
1. iThis is shaped like a V with its vertex at the point (0,5)
( its ( 1,7)
2. -3 <= -1-1 = =2
so its (-1, -3)
Answer: A or 1:4
Step-by-step explanation: Since its 16 servings and the recipe is 8, you just multiply everything by 2. Since 1/2 * 2 = 1 and 2 *2 = 4, it would be 1:4
For this case, the parent function is given by:

We apply the following function transformation:
Vertical compressions:
To graph y = a * f (x)
If 0 <a <1, the graph of y = f (x) is compressed vertically by a factor a. (Shrinks)
We have then:

Horizontal translations:
Suppose that h> 0
To graph y = f (x + h), move the graph of h units to the left.
We have then:

Vertical translations:
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
We have then:
Answer:
Vertical compression by factor of 1/2. Horizontal displacement 3 units to the left. Vertical displacement 2 units up.
