First, we need to find the slope:
m=rise/run OR

m=(2+2)/(-6-2)
m=4/-8
m=-1/2

second we need to find the equation for the line using point-slope form:


y-(-2)=-(1/2)(x-2)



to find "a" we plug in the given y value and solve for x (in this case x=a):






so, a=6 and the point becomes (6,-4)

Use the distributive property to remove the parentheses.
Alona [7]
Answer:
I believe it is 14.25

Step-by-step:

3/4(3 - -16)

First do what’s in the parentheses

(3 - -16) -> (3 + 16)
because two negatives make a positive (aka when you subtract -16 from 3 it becomes positive 16)

Then (3 + 16) = (19)

3/4(19) you multiply and get 14.25

What are two ways of determining the distance between two points
Oksanka [162]

Answer:

The linear distance between the two points is the square root of the sum of the squared values of the x-axis distance and the y-axis distance. To carry on the example: the distance between (3,2) and (7,8) is sqrt (52), or approximately 7.21 units.

Find the slope of (-4,3) and (2,6)
Wittaler [7]

Answer:

The slope is 0.5

Step-by-step explanation:

FIrst you do y2-y1/x2-x1

That makes it 6-3/2-(-4)

Simplified it's 6-3/2+4

6-3=3 and 2+4=6

So  you get 3/6=0.5
