Answer:
2
Step-by-step explanation:
Solving the given equation for y, you have ...
2x +4y = -64
4y = -2x -64
y = -1/2x -16
The coefficient of x is the slope of the given line: -1/2. The slope of the perpendicular line is the opposite reciprocal of this:
-1/(-1/2) = 2
The slope of the perpendicular line is 2.

Let's solve your equation step-by-step.
8.88=4.44(x−7)
Step 1: Simplify both sides of the equation.
8.88=4.44(x−7)
8.88=(4.44)(x)+(4.44)(−7)(Distribute)
8.88=4.44x+−31.08
8.88=4.44x−31.08
Step 2: Flip the equation.
4.44x−31.08=8.88
Step 3: Add 31.08 to both sides.
4.44x−31.08+31.08=8.88+31.08
4.44x=39.96
Step 4: Divide both sides by 4.44.
#2
= y = -3
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2 from both sides.
Step 3: Divide both sides by 5.
