A line passes through (-9,-5) and (2,-4)
zlopas [31]

The point-slope form of a line:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-9, -5) and (2, -4). Substitute:

m=\dfrac{-4-(-5)}{2-(-9)}=\dfrac{1}{11}\\\\y-(-5)=\dfrac{1}{11}(x-(-9))\\\\\boxed{y+5=\dfrac{1}{11}(x+9)}\leftarrow\boxed{\text{point-slope form}}

The standard form of a line:

Ax+By=C

y+5=\dfrac{1}{11}(x+9)                <em>multiply both sides by 11</em>

11y+55=1(x+9)

11y+55=x+9     <em>subtract 9 from both sides</em>

11y+46=x      <em>subtract 11y from both sides</em>

46=x-11y

\boxed{x-11y=46}\leftarrow\boxed{\text{standard form}}

Answer:

  P = (8, 0)

Step-by-step explanation:

The coordinates of point P are the weighted average of the end points. The weights are the reverse of the segment divisions.

  P = (2/5)A +(3/5)B

  P = (2(-4, -6) +3(16, 4))/5 = (-8+48, -12 +12)/5 = (40, 0)/5

  P = (8, 0)

Effectus [21]

Answer:

786.384

Step-by-step explanation: To get this answer, what I did is that I multiplied 3 times 12 (because that's how many inched are in a yard). Then I multiplied 36 times 2.54 to get 91.44. Then I multiplied 91.44 times 8.6 to get 786.384.
