Given the data set (5,9), (13,12), (23,16), which of the following equations best represents line of best fit?

y=3/4x-7
y=4/5x+7
y=2/5x+7
y=2/3x-7

Icould really use some with this question.

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

Write the expression as a single natural logarithm. 2 in a - 4 in y
