Answer:
2
Step-by-step explanation:
The slope of a line can be found by finding the change in change in the y values over the change in the x values:
Where y2 is the second y point and y1 is the first point, same the with x values
So:
7-3 = 4
5-3 = 2
4/2 = 2
So the slope is 2

Answer: The three numbers are 8, 12 and 20.
Explanation:
Let k be the ratio of the numbers
The numbers: 2k, 3k, 5k
(2k)^2 + (3k)^2 (5k)^2 = 608
4k^2 + 9k^2 + 25k^2 = 608
38k^2 = 608
k^2 = 16
k = 4
Hence, the three numbers are 8, 12 and 20.
