y - 8 = -x - 9

y = -x - 1

Answer:

See below for answers

Step-by-step explanation:

4) If the lengths of the triangular truss were uneven, it could collapse, thus the perimeter is needed

5) Perimeter is the total length of all the side lengths, thus 13+13+20=46 feet is the perimeter of the truss

6) The formula, like I mentioned in #5, is P=a+b+c

I need help please thanks
strojnjashka [21]

Answer:

y = 1/2x + 0

You can see the slope is rising by 1 and running (to the right) by 2. This makes the slope, or rate of change, 1/2x.

There aren`t really calculations necessary to find the rate of change, but if you need more explaining please do ask, I`m happy to help

If the line joining the points (2,y) and (4,6) has the slope -3/2 find the value of y​
Yanka [14]

Answer: y=9

Step-by-step explanation:

slope=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }

\frac{-3}{2} =\frac{6-y}{4-2}

-6=2(6-y)

-6=12-2y

2y=18

y=9
