Which function BEST expresses the linear relationship displayed by the scatter plot?
Harrizon [31]

Answer:

C

Step-by-step explanation:

We want a line of best fit, which means we want to create a line that the data points will lie closest to.

One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.

Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:

(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4

Eliminate A and B.

Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.

The answer is C.

MDI<br> Solve the following system<br> -2x + 2y = -2<br> 2x + 3y = 12
s344n2d4d5 [400]

Answer:

x = 2.25, y = 2.5

Step-by-step explanation:

-2x + 2y = -2 .............equ (1)

2x + 3y = 12 .............equ (2)

equ (1) + equ (2)

-2x + 2y = -2

+ 2x + 2y = 12

=> 0 + 4y = 10

=> 4y/4 = 10/4

=> y = 2½

Substitute for y in equ (2)

i. e, 2x + 3y = 12

=> 2x + 3(10/4) =12

=> 2x + 30/4 = 12

=> 2x = 12 - 30/4

=> 2x = (48 - 30)/4

=> 2x = 18/4

=> 8x = 18

=> x = 18/8

=> x = 2^2/8 or 2.25

x = 2.25, y = 2.5
