Answer:

slope of -1/8

and it crosses:

(3,5)

Plug the above data into the "point-slope" form:

y - y1 = m(x - x1)

y - 5 = (-1/8)(x - 3)

y - 5 = (-1/8)x + 3/8

y = (-1/8)x + 3/8 + 5

y = (-1/8)x + 3/8 + 40/8

y = (-1/8)x + 43/8

Given the midpoint (1.5,1.5) and the endpoint (5,7) where is the other endpoint located

earnstyle [38]

The formula of a midpoint:

$M_{AB}\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)$

We have:

$M(1.5,\ 1.5)\to x_M=1.5,\ y_M=1.5\\A(5,\ 7)\to x_A=5,\ y_A=7$

Substitute

$\dfrac{5+x_B}{2}=1.5\qquad|\cdot2\\\\5+x_B=3\qquad|-5\\\\x_B=-2\\\\\dfrac{7+y_B}{2}=1.5\qquad|\cdot2\\\\7+y_B=3\qquad|-7\\\\y_B=-4$

Firlakuza [10]

The formula of a midpoint between X and Y:

$M_{XY}\left(\dfrac{x_X+x_Y}{2},\ \dfrac{y_X+y_Y}{2}\right)$

We have the points X(7, 10) and Y(5, -8). Substitute:

$\dfrac{7+5}{2}=\dfrac{12}{2}=6\\\\\dfrac{10+(-8)}{2}=\dfrac{2}{2}=1$
