Please show work

Answer 1

If the given numbers are the x coordinates.
Sub. the values given one by one into the given equation to get the respective value of y.
Take -7 as an example
Y=-4/7x-5
=-4/7 (-7)-5
= 4 -5
= -1

Can you do the rest?

Answer 2

im still lost

Answer 3

in where?

Answer 4

i got a fraction when i did it for the zero

Answer 5

Can you show your workings?

Answer 6

y=-4/7x-5
=-4/7(0)-5
=-4/7-5
=4 3/7

Answer 7

i got -9 when i did it for the 7

Answer 8

-4/7 (0) = ...?

Answer 9

For 7, you did it right :)

Answer 10

-4/7(0)=0

Answer 11

Yes. So,
y=-4/7x-5
=-4/7(0)-5
=0-5
=...

Answer 12

-5

Answer 13

Yes :)

Answer 14
