The answer is y = -5.5x - 52.

First, let's find the slope of the line.

m = Δy/Δx

  • m = -8 - 3 / -8 - (-10)
  • m = -11 / -8 + 10
  • m = -11/2
  • m = -5.5

Now, substitute the slope and one of the given points in the point slope equation.

<u>y - y₁ = m (x - x₁)</u>

  • y - 3 = -5.5 (x - (-10))
  • y - 3 = -5.5 (x + 10)
  • y - 3 = -5.5x - 55
  • y = -5.5x - 52

Answer: y=-5,5x-52.

Step-by-step explanation:

                        Equation of a straight line

                               \displaystyle\\\boxed {\frac{x-x_1}{x_2-x_1}=\frac{y-y_1}{y_2-y_1}  }

(-10;3)\ \ \ \ \ (-8;-8).\\\displaystyle\frac{x-(-10)}{-8-(-10)} =\frac{y-3}{-8-3}\\ \frac{x+10}{-8+10}=\frac{y-3}{-11} \\ \frac{x+10}{2}=\frac{y-3}{-11}  \\-11*(x+10)=2*(y-3)\\-11x-110=2y-6\\2y=-11x-104\ |:2\\y=-5,5x-52.

Complete the equation of the line through (-9,-9) and (-6,0)
Rudik [331]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis.

According to the data of the statement we have the following points:

(x_ {1}, y_ {1}): (- 9, -9)\\(x_ {2}, y_ {2}): (- 6,0)

We found the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {0 - (- 9)} {- 6 - (- 9)} = \frac { 9} {- 6 + 9} = \frac {9} {3} = 3

Thus, the equation is of the form:

y = 3x + b

We substitute one of the points and find b:

0 = 3 (-6) + b\\0 = -18 + b\\b = 18

Finally, the equation is:

y = 3x + 18

Answer:

y = 3x + 18
