mylen [45]
For this case we have:
 m = (y2-y1) / (x2-x1)
 m = (15-10) / (2-1)
 m = 5/1
 m = 5
 Then,
 y-yo = m (x-xo)
 where,
 (xo, yo) = (1, 10)
 Substituting:
 y-10 = 5 (x-1)
 y = 5x -5 + 10
 y = 5x + 5
 Answer:
 
a linear function to describe the sequence is:
 
y = 5x + 5

Explain how you would find the height of a rectangular prism if you know that the volume is 60 cm³ and that the area of the base
stellarik [79]
We can find the height by looking at what we know, and what we want to know. 

We know that the volume of a rectangular prism can be found with the equation:
base width x base length x height = volume

We also know that the base's width x length = 10cm^2, so we can fill in what we know into the volume equation.
10cm^2 x height = 60cm^3

Solving this equation we find that the height if the prism is 6 cm.
