Question

URGENT, PLEASE HELP! (3/5) -50 POINTS- !please no wrong answers for the points.! A)
`y = (9)/(2) x + (1)/(2)` B)
`y = - (1)/(2) x + (7)/(2)` C)
`y = -4x + 9` D)
`y = 4x + 15`

Answer 1

`\Large \boxed{y=-(1)/(2) x+(7)/(2) }`

Explanation:

Using a graph,

we can see that the line y = -1/2x + 7/2 best fits for the data.

Answer 2

B y = -1/2x + 7/2

Explanation:

We know that it has a negative slope since the points go from the top left to the bottom right

We can eliminate A and D

The y intercept is where it crosses the y axis

It should cross somewhere between 2 and 4

C has a y intercept of 9 which is too big

Lets verify with a point

x = -4

y = -4(-4)+9 = 16+9 = 25 (-4,25) not even close to being near the points on the graph

checking B

y = -1/2 (-4) +7/2

= 2 + 7/2 = 11/2 = 5.5 it seems reasonable
