Answer:
The slope is 3 and the line is rising.
Step-by-step explanation:
To find the slope m of a line given two points (x₁, y₁) and (x₂,y₂) we can use the formula:
m = (y₂-y₁) / (x₂ - x₁)
In this problem we have the points (6,2) and (7,5), substituting these values in the formula we get:
m = (5 - 2) / (7 - 6) = 3/1 = 3
Therefore, the slope is 3.
Given that the slope is positive we can conclude that the line through the points rises.
Answer: The maximum depth that he will reach is -125 meters.
The first thing you should realize is that this is a quadratic equation and the graph will be a parabola.
We can simply the equation to:
y = (1/20)x^2 - 5x
Now, use -b/2a to find the x-value of the vertex which is 50. Then, input 50 back into the equation to get -125 for the maximum depth.
Answer:
7 + 1.5 = 8.5
