Which equation represents the situation?

Manuel’s Crates
Crates
2 4 6 8
Cost 25 45 65 85


A.
y – 2 = −10(x – 25)

B.
y – 4 = 10(x – 45)

C.
y – 65 = −10(x – 6)

D.
y – 85 = 10(x – 8)

Answer 2

I'm debating between C and D.

Answer 3

substitute an x value in for x and the corresponding y value for y and see if they equal each other

Answer 4

I did that in C and D and the answer was always the same on both sides. and there's only one answer that should be correct.

Answer 5

Use the slope formula to find the slope. Then use one of the points and plug it into the points-slope formula
With point \((x_1,y_1)\) on the line...
\(large y-y_1=m(x-x_1)\)
m= slope

Answer 6

sorry ignore the large part...
\(\large y-y_1=m(x-x_1)\)

Answer 7

A.
25 – 2 = −10(2 – 25)

B.
25 – 4 = 10(2 – 45)

C.
25 – 65 = −10(2 – 6)

D.
25 – 85 = 10(2 – 8)

A
23=-10(-23)
23=230
nope

B
21=10(-43)
21=-430
nope

C
-40=-10(-4)
-40=40
nope

D
-60=10(-6)
-60=-60
yep

Answer 8

so its D?

Answer 9

yes
can you show me your work for C?
