Answer:

upon graphing, it is linear

Step-by-step explanation:

The equation below represents the trend line of a scatter plot showing the hours spent studying versus science test scores.
navik [9.2K]

Answer:

On the science test  the point  ( 0 , 424 ) the intercepts is bigger

Step-by-step explanation:

The relation hours spend vs science test score is

y  =  6.5*x  + 424

And the relation hours spend vs Maths test score is

y  =  7.2*x   + 34.7

Making   x =  0  ( student does not study at all ) we get:

For science score test woul be

y  =  0  + 424

In case of maths

y  =  0  + 34.7

That mean student without studying will get better score in science.

The point  ( 0 , 424)   ( science ) represents the interception with y axis

in Maths case such point is  ( 0 . 34.7)

PLEASE HELPPPPPP!!!!!!Solve this system of linear equations separate the x-and y-values with a comma
GenaCL600 [577]

Answer:

x=-6,\\y=6

Step-by-step explanation:

Rewrite the system of equations as:

\begin{cases}-13x+2y=90\\-6x+2y=48\end{cases}

Subtract the second equation from the first to isolate x:

-13x+2y-(-6x+2y)=42,\\-7x=42, \\\fbox{$x=-6$}

Plug in x=-6 into any of the equations above and solve for y:

-6(-6)+2y=48,\\2y=12,\\\fbox{$y=6$}

Verify that the solution pair (-6, 6) works \checkmark

Therefore, the solution to this system of equations is:

x=-6,\\y=6
