Which expression can be simplified to find the slope of the trend line in the scatterplot?
Nutka1998 [239]

Answer:  \frac{35-21}{8-4}

Step-by-step explanation:

The slope of a line equals to the difference between points' y-coordinates divided by the difference between their x-coordinates.

That is, if (x_1,y_1) and (x_2,y_2) are the point of a line,

Then the slope of the line is,

m=\frac{y_2-y_1}{x_2-x_1}

By the given diagram,

x_1=4, y_1=21, x_2=8 and y_2=35

Thus, the slope of the given line

= \frac{35-21}{8-4}

⇒ Fourth option is correct.

Can you please help me with this two questions ​
Natali [406]

Answer:

2) d. 60°

3) a. AB

Step-by-step explanation:

<u>Question 2</u>

ΔABC and ΔCDA are <u>congruent</u> because:

  • they are both <u>right triangles</u>
  • they <u>share one side</u> (AC)
  • their hypotenuse are <u>parallel</u> (marked by the arrows)

This means the corresponding side lengths and angles are equal.

Therefore,

∠CDA = ∠ABC

⇒ x = 60°

<u>Question 3</u>

The <u>hypotenuse</u> is the <u>longest side</u> of a <u>right triangle</u> - the side opposite the right angle (the right angle is shown as a small square).

Therefore, the hypotenuse of ΔABC is the line AB.
