Question

Two quantities are related, as shown in the table:

x y
2 10
4 9
6 8
8 7


Which equation best represents the relationship?

Answer 1

the table is showing a linear relationship.

so find the slope by picking any 2 points....

that's the 1st part

Answer 2

y=1/2x+11
y=-1/2+11
y=2x+10
y=2x+11

Answer 3

do you know how to find the slope of a line..?

Answer 4

i'm trying to figure this out to help show my son how to do I didn't have to learn this when I was in school.

Answer 5

ok... so use the points (2, 10) and (4, 9)

the slope is the change in the y values divided by the change in x values

\[m = \frac{10 - 9}{2 - 4}\]

when you calculate the slope you eliminate 2 answers...


the the slope intercept form is

y = mx + b

so substitute the slope you just found

then use any point like (6, 8) and substitute these to find b

it means x = 6 and y = 8

hope it helps

Answer 6

ty for explaining it to me.
