I believe the answer is 60
Point-slope form: y - y₁ = m(x - x₁)
m is the slope, (x₁ , y₁) is your point
So your point-slope equation is:
m = -4 (x₁ , y₁) = (4 , -9)
y - y₁ = m(x - x₁)
y + 9 = -4(x - 4)
(this is for fractions!!!!!!!!!!!!) 28/5 or 5 3/5
i think u just make it into 5.6/1 multiply by 10 which gets 56/10 and wala
but it's not simplified. 56 and 10 is divisible by 2 so u get 28/5 which is actually 5 3/5 (which is 5.6!!)
Angles of Elevation and Depression. The angle of elevation of an object as seen by an observer is the angle between the horizontal and the line from the object to the observer's eye (the line of sight).
