Answer:
y=15x+126
Step-by-step explanation:
the slope is
15 because -8-(-9) is 1 and 6-(-9) is 15 and y is over x so slope 15
To find y intercept start from -8,6 and add 15 to the y value every time you add one to the x value
you will add 8 times and you get 126 as the intercept
The answer to your question is letter A (2/3)
Formula
tangent Ф =
For A
opposite side = 2
adjacent side = 3
Substitution
tan Ф =
Result
400,000,000+30,000,000+200,000+90,000+100
