You must show all your working.
B.The two lines have opposite slopes.
C.The two lines have zero slopes.
D.The two lines have the same slope.
Answer:
Option (d) is correct.
The two lines have the same slope.
Step-by-step explanation:
Given : two parallel lines
We have to choose one statement that is true regarding Parallel lines.
Parallel lines are those lines that do not intersect each other and distance between them remains same throughout the plane.
Also , parallel lines have same slope.
From the graph attached below both lines have parallel and have same slope.
equation of line :
2x + 3y = 10 and 6x + 3y = 10
Both are parallel and have slope -2
Thus, Option (d) is correct.
The two lines have the same slope.

To round 494.37 to 1 significant figure, it becomes 400. To round 5.12 to 1 significant figure, it becomes 5. When we divide 400 by 5, we get 80.
For rounding 1 significant figure, we look at the first non-zero digit in the number. In this case, the first non-zero digit is 4. We keep that digit and drop all the digits to the right of it. So, 494.37 becomes 400.
Similarly, for 5.12, the first non-zero digit is 5. We keep that digit and drop all the digits to the right of it. So, 5.12 becomes 5.
Now, we divide 400 by 5, which gives us 80.
