Find the slope and y-intercept of the line through the points (-3,-4) and (0,-1)​
Alja [10]

Answer:

Slope=1, y-intercept=-1.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-4))/(0-(-3))

m=(-1+4)/(0+3)

m=3/3

m=1

y-(-4)=1(x-(-3))

y+4=x+3

y=x+3-4

y=x-1

y=mx+b where m=slope and b=y-intercept

so you have slope of 1 and y-intercept of -1

Use De Morgan's laws to write negations for the statement. Sam is an orange belt and Kate is a red belt.
iVinArrow [24]

Answer:

C. Same is not an orange belt and Kate is not a red belt.

Step-by-step explanation:

A negation is an operation that "takes a statement and changes it to a statement whose true or false value is opposite". For example, if I were to say 2 + 2 = 4, the negation would be that 2 + 2 ≠ 4.

So, if Sam is an orange belt and Kate is a red belt, the negation is C. Same is not an orange belt and Kate is not a red belt.

Hope this helps!

Chris read 1 /4 of a book in the morning, and he read some more at night. By the end of the day, he still had 1 /3 of the book l
Grace [21]

Answer:

5/12

Step-by-step explanation:

1/4 (what he already read)= 3/12

1/3 (what he had left) = 4/12

12/12 (whole book) - 4/12 (what he has left to read)= 8/12 (what he already read+what he read during the day)

8/12 - 3/12 (what he already read)= 5/12 (what he read during the day)

answer: 5/12
