Second option, just do Pemdas backwards.
Answer:
-2
Step-by-step explanation:
because the slope is 2, a perpendicular line must be the inverse
the equation for y1 is y=2x+1
y2= -2y+1
If the line has a slope of -9, the slope of any parallel line will also be -9.
Parallel lines always have the same slope.
The correct proportions are given as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The proportions for this problem are given dividing y by x, hence:
- x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.
- x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.
- x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.
- x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.
- x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.
- x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.
