Answer:

Step-by-step explanation:

SST = ∑ ( y − ȳ ) ² (ȳ = pronounced y bar is the mean of y values)

ȳ = (5+9+10)/3 = 24/3 = 8

∑ ( y − ȳ ) ² = ( 5 − 8 ) ² + ( 9 − 8 ) ² + ( 10 − 8 ) ²

= ( − 3 ) ² + ( 1 ) ² + ( 2 ) ²

= 9 + 1 + 4

= 14

A) {y=2x

sladkih [1.3K]

We can see that

both lines intersects at origin

so, the solution is x=0 and y=0

now, we will check each options

option-A:

$y=2x$

$y=-4x$

now, we can set them equal

and then we can solve for x

$-4x=2x$

$6x=0$

$x=0$

now, we can find y

$y=2*0$

$y=0$

so, solution is x=0 and y=0

so, this correct...........Answer
