1 answer:
Answer:
Step-by-step explanation:
Given:
Slope (m) = -2
Point on the line = (4, -6)
Required:
Point-slope equation of the line
Solution:
Point-slope equation takes the following form:
,
Where,
m = slope of the line = -2
(a, b) = coordinates of the point on the line. = (4, -6)
Plug in the values into the slope-point equation

Answer:
14
Step-by-step explanation:
To get the answer, add the whole numbers together and then add the fractions together:
9 + 4 = 13
(You can even stop here because 14 is the closest to 13)
Now, add the fractions:
To add fractions you have to have a common denominator. To find the common denominator multiply 3 by 5, and 5 by 3. Like this:
Simplify:
Distribute everything from above
Add
So, the whole fraction will look like this . This is closest to 14.
