Answer:
y = 10/2x + 0
Step-by-step explanation:
Slope Int Form: y = m(slope)x + b(y-intercept)
The number before the x is the slope. To find the slope, count how far up or down and how far to the right or left. The b in the equation is the y-int so find the y-int of the graph.
144 miles as you can see from the slope in the graph
We have the triangle 30° - 60° - 90°.
The lenght of the sides are in proportion:
