The value of missing coordinate "r" is -4
<em><u>Solution:</u></em>
Given that,
The points (1, r) and (4, -13) lie on a line with slope – 3
To find: missing coordinate r
The slope of a line is given by formula:
Where, "m" is the slope of line
Here in this sum,
m = -3
Substituting the values in formula,
Thus the value of missing coordinate "r" is -4

Answer:
525
Step-by-step explanation:
Since the submarine is 150 (you didn't specify the units) <em>below</em> sea level, we can express its position as -150. Therefore, 375 - (-150) = 375 + 150 = 525.
Answer:
4x + 1 = 9
Step-by-step explanation:
3x + 12 -12 = 18 - 12 ---> 3x = 6 ---> x = 2.
Since x = 2, 4x + 1 is the same as (4 * 2) + 1.
(4 * 2) + 1 = 9.
