Someone which function best expresses the linear relationship displayed by the scatter plot? a) y= x+ 10 b) y= x+ 19 c) y= 10x + 19 d) y= 19x + 10

Option: A is the correct answer.

                    A) y= x+ 10

Step-by-step explanation:

We are given a set of data values on the scatter plot as follows:

           x      y

           9     19

           9     20

           11     21

           12    21

           13    23

         14.5   24

           15     25

           16     25

Now the line of best fit that best represents these data points are:

                     y=x+10

Also, the r-value of this line of best fit is close to 1.

Hence, the function that best expresses the linear relationship displayed by the scatter plot is:

                               y=x+10

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
