D. -2/3 because when you do (y2-y1)/(x2-x1) you get -4/6 which simplifies to -2/3
It would be 0.81 because she got 81/100 right. Hope this helpz..
Triangle: 13.3 km Why: the formula is 1/2 base x height.
Square: 57.4 Why: 7x8.2 which equals 57.4
Answer:
Hey there!
A line perpendicular to y=3x+5 would have a slope of -1/3.
Thus, the problem now becomes to write a line in point slope form with a slope of -1/3, and that passes through (4, -1)
y+1=-1/3(x-4), would be your answer.
Hope this helps :)
