1.Find the slope of the line through (-6, 11) and (15, 20).
GrogVix [38]

Answer:

\boxed {\boxed {\sf m= \frac{3}{7} }}

Step-by-step explanation:

We are asked to find the slope of a line. The slope tells us the steepness and direction of a line. It is found by dividing the change in y by the change in x.

m= \frac{ \Delta y }{\Delta x}

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

In this formula, (x₁, y₁) and (x₂, y₂) are the points the line passes through. We are given the points (-6, 11) and (15,20). If we match a value with its corresponding variable, we see that:

  • x₁ = -6
  • y₁ = 11
  • x₂ = 15
  • y₂ = 20

Substitute the values into the formula.

m= \frac{20-11}{15 - -6 }

Solve the numerator.

m= \frac{9}{15--6}

Solve the denominator. 2 back to back negative signs become a positive sign.

m= \frac{9}{15+6}

m= \frac{9}{21}

Simplify the fraction. 3 divides evenly into the numerator and denominator.

m= \frac{9/3}{21/3}

m= \frac{3}{7}

The slope of the line is <u>3/7.</u>

<h2><u>r = -0.4</u></h2>

Step-by-step explanation:  57.7r + 23.23 = 2.57          57.7/57.7  = -20.66/57.7

                                                        - 23.23  - 23.23
