Answer:

SSS

Step-by-step explanation:

I can identify that these triangles are congruent by using the SSS (Side, Side, Side) postulate theorem. I know this because first, second, and home triangle share the same side as the third, second, and home triangle, meaning they are congruent, so are the other sides of the angle since the question states they are congruent.

Match each equation to the line of best fit that it models.
egoroff_w [7]

By applying concepts of <em>linear</em> functions, the graphs are related to the following expressions:

  1. (4/7) · x + 2
  2. x + 2
  3. (1/7) · x + 2
  4. - (1/7) · x + 2
  5. - x + 2

<h3>How to match a line with a given linear function</h3>

Graphically speaking, lines are described by <em>linear</em> functions, a kind of polynomials of grade 1, whose standard form is presented below:

y = m · x + b     (1)

Where:

  • x - Independent variable
  • y - Dependent variable
  • m - Slope
  • b - Intercept

Please notice that the slope is represented graphically by the change in the y-variable divided by the change in the x-variable and the intercept is the location where the line passes through the y-axis. Hence, the <em>resulting</em> expressions are shown in this order:

  1. (4/7) · x + 2
  2. x + 2
  3. (1/7) · x + 2
  4. - (1/7) · x + 2
  5. - x + 2
