Answer:
Step-by-step explanation:
Given
Represent the months with x and the earnings with y.
So:
Required
Determine the linear function
First, calculate slope (m)
The equation is then calculated using:
As a function, we have:
Find the distance between these points A (5,8), B (-3, 4)
1 answer:
I don't know the distance formula off the top of my head, so I'll draw a triangle and use the pythaorean theorem. This is what the points look like when plotted. Draw a line that connects them (will be hypotenuse) and draw two legs that connect to make a triangle. After you draw the legs, find their length and input it into the pythagorean theorem.
a² + b² = c²
4² + 8² = c²
16 + 64 = c²
80 = c²
The distance (hypotenuse) is √80 or approximately 8.95, rounded to 9 units.
Hope this helps!
