Y-intercept is where it goes through the y axis. So if you look at the image, it cuts through the y-axis at (-24, 0), so that is the y-intercept,
Answer:
71°
Step-by-step explanation:
The angle of elevation of the hill can be obtiaed using trigonometry :
Given
the opposite length = 14.5 feets
Adjacent = 5 feets
The angle of elevation vabnbe obtained using :
Tan θ = opposite / Adjacent
Where θ = angle of elevation
Tan θ = 14.5 / 5
Tan θ = 2.9
θ = tan^-1(2.9)
θ = 70.97 = 71°
Since 7 yd is 21 ft you will have to
add 15 ft to 21 ft (36 ft)
and then divide by two
your answer is 18 ft
8 x a = 8 x (-2) = -16
-16 + b = -16 + 3 = -13
-13 is the answer
