For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal. A line parallel to
, will have the same slope -3. Thus, the equation will be of the form:
We substitute the given point and find "b":
Finally, the equation is:

3 significant figures is 3 numbers.
Answer:
7 3/4
Step-by-step explanation:
-5/8 + 8 3/8
= -5/8 + 7 11/8
= 7 6/8
Simplify
7 3/4
Answer:
x + (x + 1) = 71
Step-by-step explanation:
One number is x
So, other number = x + 1
Since, the sum of two consecutive number is 71
Therefore, x + (x + 1) = 71
Answer:
4a) P (Y and Y) = 1/9
4b) P (Y or Y) = 2/3
4c) P (B and Y) = 1/18
Step-by-step explanation:
4a) P (Y and Y) = 2/6 x 2/6
4b) P (Y or Y) = 1/3 + 1/3
4c) P (B and Y) = 1/6 x 1/3
'and' requires multiplying probabilities
'or' requires adding probabilities
