Answer: two over three
Step-by-step explanation:
line intercepts y at (0,-2)
Therefore,
Substitute x = 3 in y =ax-2
To find the x-intercept, y = 0
The slope is 2/3
y-intercept is -2
So two over three

Answer:
2.17ft/s
Step-by-step explanation:
Look at the sketch of ladder at the beginning and after 3 seconds it starts to fall,
Distance of ladder from the wall 3 seconds after ladder starts to fall = Initial distance+ Velocity× time
= 6 + 2×3
= 12ft
Use trignometry to find out the speed of the top of ladder
cosθ= 12/20
θ= 0.825 rad
tan θ= v/2
v= 2.17ft/s
