Romashka [77]3 years ago

Answer:

D

Step-by-step explanation:

Correlation coefficient is the leading coefficient of the line of best fit. We can estimate the slope by looking at the plots. The plots are moving in a positive slope so we can remove B and C and E.

We're left with slope of 1 and 0.5

We can faintly imagine the line of slope 1. It doesn't really fit. SO it is 0.5

Complete the slope-intercept form of the linear equation that represents the relationship in the table.
nevsk [136]

According to the given table, the slope-intercept equation of the line is given by:

y = -2x + 1

The equation of a line, in <em>slope-intercept</em> form, is given by:

y = mx + b

In which:

  • The slope is m.
  • The intercept is b.

In this problem, we are given two points, (3,-5) and (-2,5).

  • The slope is given by <u>change in y divided by change in x</u>, hence:

m = \frac{5 - (-5)}{-2 - 3} = -2

Hence:

y = -2x + b

Point (3,-5) means that when x = 3, y = -5, which is used to find b.

y = -2x + b

-5 = -2(3) + b

b = 1

Hence, the equation of the line is:

y = -2x + 1

Which of the following best describes similar figures that are not congruent?
Drupady [299]

Answer:

A

Step-by-step explanation:

Being similar means that the shapes will have the same shape and dilation factor between sides, but if they are not congruent then the size will not be the same.
