Answer:
Step-by-step explanation:
y = mx + b <-- slope intercept form
Looking at the line from point (0,-5) to (3,0)
The slope (mx), rise over run
Rises 5 (in the positive direction, up) and runs 3 (in the positive direction, right)
the slope being 5/3
Then the b being your y-intercept
-5 will be your b because the line crosses the y axis at (0,-5) but the y-intercept is -5
Overall: y =
x + (-5)
or
y = 5/3 x - 5
Answer:
m∠BFE = 171º
BE = 219º
Step-by-step explanation:
∠BFE is supplementary to ∠EFC
m∠BFE = 180 - 9
m∠BFE = 171º
--------------------------
The angle between two chords is equal to half the sum of the intercepted arcs:
∠BFE = (DC + BE)2
171 = (123 + BE)/2
342 = 123 + BE
219º = BE
8 / 4 = 2.
6 ft * 2 = 12ft
The flagpole is 12ft tall
