Let's give some distances
100 up 100 flat 100 down meters
then return 100 up 100 flat 100 down
time required (distance/rate = time ) 200/100 + 200/120 + 200 / 150 = 5 hr
distance 600
distance / time = average speed = 600/5 = 120 m/s
Ill assume it is :-
tan^2 A - 2 tan A + 1 = 0
(tan A - 1)^2 = 0
tan A = 1
m < A = 45, 225 degrees ( where 0 < m A < 360 )
(-2,0) instead of substitution, you can use elimination which the 3x's will cancel out and you solve the system regularly
Hey!
-------------------------------------------------
Point Slope Form: y - 7 = -5/2(x + 4)
Slope-intercept Form: y = mx + b
m = slope
b = y-intercept
We can automatically eliminate Option A and B because they are both written in point slope form when the questions asks for slope-intercept form.
We can also eliminate option C because the slope in the equation doesn't match the slope in the equation above.
-------------------------------------------------
Answer:
y = -5/2x - 3

Hope This Helped! Good Luck!
