Answer:

78

Step-by-step explanation:

Let x be the score on the next test

We are averaging 6 tests and want an average of 75

( 82+91+38+78+83+x) /6 = 75

Multiply each side by 6

( 82+91+38+78+83+x) = 75*6

( 82+91+38+78+83+x)  =450

Combine like terms

x+372 = 450

Subtract 372 from each side

x+372-372 = 450-372

x =78

arlik [135]

To find the slope of the expression:

f(x)=y=3x-1

We need to remember that this is the Slope-intercept Form of the line equation:

y=mx+b

Where

m = slope

b is the y-intercept.

Therefore, the slope of the line equation above is m = 3.
