Determine the y-intercept
lesya692 [45]

Answer:

-21

Step-by-step explanation:

the y intercept is when x=0.

you can see that this is a linear equation where each increase in x results in  an increase of 4 onto the y value.

so if when x=1, y=-17, subtract 4 to find what y equals when x is 0.

-17 -4=-21

good luck :)

Please help me find the answers!
frozen [14]

Answer:

15/7

Step-by-step explanation:

To divide fractions, the process is as follows:

1) Flip one of the fractions over (numerator becomes denominator, denominator becomes numerator). In this problem, this step looks like:

5/7 divided by 1/3 ---> 5/7 divided by 3/1

2) Once one fraction is flipped, change the division sign to a multiplication sign. In this problem, this step looks like:

5/7 divided by 3/1 ---> 5/7 * 3/1

3) Multiply the fraction (multiply one fraction's numerator and denominator by the other's) In this problem, this step looks like:

5/7 * 3/1 ---> 15/7.

To check, use the same steps in the problem ? * 1/3 = 5/7. You'll find that 15/7 * 1/3 = 5/7.
