Answer: 13.69
Step-by-step explanation:
Multiply 82.14 by 100 to make it a whole number; since you're modifying the number, you must also multiply 6 by 100 in order to keep it balanced.

Answer:
y = ix + 6i + 4
Step-by-step explanation:
Since the line has undefined slope or indefinite slope we connote that the slope is (i)
Slope(m) of straight line = change in y ÷ change in x
Taking another point (x,y) on the line:
i =
i =
Cross multiplying gives;
y - 4 = ix + 6i
y = ix + 6i + 4
Answer:
Slope = -1
Step-by-step explanation:
Since, slope of a line passing through two points and
is given by,
Slope =
Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,
Slope =
= (-1)
Therefore, slope of the line is (-1).
