Answer:
points (2,2) and (-2,-4):
y-intercept= -1, the equation is y= 3/2x -1
points (-2,0) and (0,-5):
y-intercept = -5, the equation is y= -5/2- 5
points (0,3) and (i can’t read the other one)
y-intercept= 3, the equation is y=4x+ 3!

13 km
Step-by-step explanation:
The area formula for a triangle is ...
A = (1/2)bh
We are told that b=2h, so this becomes ...
A = (1/2)(2h)(h) = h²
Substituting the given area, we can find h:
169 km² = h²
(√169) km = h = 13 km
The height is 13 km.
x=9
27-9=18 and 18-9=9 so x =9
(x + 3) (x² - 2x - 6)

First we less the sum of 56% and 16% from 100% to get our percentage of visitors under 12.
Percentage of visitors under twelve = 28%
Then we take 28% of 1,575.
Easiest done if we use the fraction .28 instead of 28%.
Number of visitors under twelve= 441
3^2
3^-4*3^6
3^-4+6
