In order to find the equation of a line, you would have to use the equation y=mx+b.
First, find the slope:
There is (1,8) and (2, 16) so plug that in 16-8/2-1 = 8. That's your slope! (Or the m)
Next in order to find b, you have to plug in a point:
y=8x+b
Take (1,8) and plug it in for x and y:
8=8(1)+b
b=0
Your y intercept is 0 (which you can also see on the graph)
So your answer is: y=8x
The answer should be the sum of 5 and 12 is n
Answer:
A) horizontal shift right 6
i) reflection over the x axis
E) vertical strech by 1/2
D) vertical shift up 5
Step-by-step explanation:
f (x) = -1/2 . 4 ^ (x - 6) +5
fx=−1/24^(x−6)+5
y=−1/2 4^(x−6)+5
ok
the negative makes a reflection over x-axis
vertical stretch by 1/2
+5= up 5 vertically
(x-6) makes it go right 6

Since the sum of the angles of a triangle is 180 degrees, we simply have to add all the angles and equate it to 180 to solve for x. So:
100 + 12x + 4 + 14x - 2 = 180
26x = 78
x = 3
So, x is equal to 3.
So, our friendly number will be 300: it's only two numbers away from 298!
We multiply 300 by 6: it's 1800. (3*6=18, and the 0s we can just add at the end)
now we only need to subtract those two numbers (mupliplied by 6): so we subtract 12.
the result will be 1800-12=1788.
