A bridge is suspended from cables between two towers, each 30 feet high. The height of the suspension cable above the bridge surface is a function of distance, d, from the left end of the bridge with rule: h (d) = 0.01d² — d + 30. What are the coordinates of the function at its minimum value?

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

m1=5,m2=0

answer: answer is b.

[m < b = 120º]
