Answer:

y = 1/5x + 8

Step-by-step explanation:

slope = (change in y)/(change in x)

Slope = (8 -10)/(0 -10)

Slope = -2/-10

Slope = 1/5

Use y = mx + b   substitute m = 1/5  and (0, 8)

      8 = 1/5(0) + b

      8 = 0 + b

      8 = b

The equation of the equation  y = 1/5x +8

Answer:

f(2) = 81

g(2) = 83

Science class had a higher average

Step-by-step explanation:

Given

f(x) = 0.5x + 80

g(x) table

Solving (a): f(2)

We have:

f(x) = 0.5x + 80

So:

f(2) = 0.5*2 + 80

f(2) = 1 + 80

f(2) = 81

Solving (b): g(2)

From the given table.

g(2) = 83

Solving (c): f(4) or g(4); which is greater

f(x) = 0.5x + 80

So:

f(4) = 0.5*4+80

f(4) = 2+80

f(4) = 82

For g(4): Notice that in the table of g(x); g(x) increases by 2 when x increases by 1

This means that:

g(x) = g(x-1)+2

So

g(4) = g(4-1)+2:

g(4) = g(3)+2

g(4) = 85+2

g(4) = 87

<em>Hence, g(4) i.e. Science class is greater</em>
