Volgvan

Answer:

$( \frac{1}{2} x + 1 \frac{2}{3} ) - (1 \frac{1}{2} x - 1 \frac{1}{3} ) \\ = ( \frac{1}{2} - \frac{3}{2} )x + ( \frac{5}{3} + \frac{4}{3} ) \\ = \frac{ - 2}{2} x + \frac{9}{3} \\ = - x + 3 \\ = 3 - x$

VT is the diagonal of a rhombus.<br> What is the slope of the other diagonal?

noname [10]

Answer:

C

Step-by-step explanation:

Remark

The slope of the given segment is found by using the 2 end points.

V(3,2) and T(5,7)

Slope of VT

<u>Givens</u>

y2 = 7
y1 = 2
x2 = 5
x1 = 3

<u>Formula</u>

m = (y2 - y1)/(x2 - x1)

<u>Solution</u>

m = (7 - 2)/(5 -3)

m = 5/2

Slope of other diagonal

m * m1 = - 1

5/2 * m1 = - 1

5m1 = -1*2 = -2

m1 = -2/5
