Atriangle has height 15 in. and area 120 in. what is the length of its base?

Fist put it in the triangle area formula: A = b * 1/2h
plug in your numbers:
120 = b * 15 or bc you didnt say if it was divided by 1/2 or not i will do both so it could be this too: 120 = b * 7.5 since 7.5 half of 15
solve:
120= b*15
b=8
OR
120=b*7.5
b=16
so 8 or 16 is your answer
depends if 15 was already in half or wasnt

We need more info then that

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
