As we know the formula to calculate the line of equation is y - y1 = m (x - x1)
Where m is the slope. y1 is the first y co ordinate. x1 is the first x co ordinate.
Now we do know that the slope of parallel line is the same as the slope of the original line.
So parallel line slope is 3 so slope for our line is 3. Hence equation is y - 7 = 3 (x - 2) which becomes y = 3x + 1.
Move the negative sign to the left
-x/5 = -20
Multiply both sides by 5
-x = -20 × 5
Simplify 20 × 5 to 100
-x = -100
Multiply both sides by -1
<em>x = 100</em>

All of these questions will be exponents and variables.
Answer: 2.25 meters
Step-by-step explanation: 1 in = 2 meters. 0.75 is 75 percent of 1 so the length of the window is 75 percent of 2 which is 1.5. 1.5 squared is 2.25 so the length of the window is 2.25 meters
