Answer:

f(x)=1x-8

Step-by-step explanation:

slope: 0-(-7)/ 8-1 = 7/7= 1

eg. (1,-7)

-7= 1 -y int.

y int. = 8

therefore:

f(x) = 1x-8

Add the following rational number = 3/11 and -5/12

tatiyna

Answer:

-19/132

Step-by-step explanation:

To add fractions, find the lowest common multiple of the two denominators and multiply accordingly to make both denominators the same. In this case, the lowest common multiple of 11 and 12 is 132, so we need to multiply the first number by 12 and the second by 11. So we get $\frac{36}{132} + (-\frac{55}{132} )$ = $\frac{36-55}{132}$ = $\frac{-19}{32}$ $-\frac{19}{132}$
