Question

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

y - 6.5x+424

The equation below represents the trend line of a scatter plot showing the hours spent studying versus math test scores.

y = 7.2x+34.7

If a student does not study for either test, on which test should the student expect the higher score?

o on the science test because the rate of change is greater

O on the math test because the rate of change is greater

on the science test because the y-intercept is greater

o on the math test because the y-intercept is greater

Answer 1

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)

Answer 2

Answer:

on the science test because the y-intercept is greater

Step-by-step explanation:

Just cause
