What is the equation of this line?<br> Please Help <br><br> Y=4x<br> Y=-1/4x<br> Y=-4x<br> Y=1/4x
Sveta_85 [38]

Answer: Y=-1/4x

Step-by-step explanation:

A good way to find an equation of a line is to look for the slope. An obvious spot on this line would be when it crosses (0,0), and another one to the right would be when it crosses at (4,-1).

The slope is rise over run, or if we use the two points we found, "rise" would be -1, because it's dropping 1 unit when going from (0,0) to (4,-1), and the "run" would be 4, because it moves to the right 4 from (0,0) to (4,-1).

Putting these two values together we get:

m (slope) = rise / run

m = -1 / 4

Out of all the equations we're given, we can look for the one with a slope of -1/4, which is given to us:

y = (-1/4)x

A farmer needs 3x2 − 4x + 10 seeds for each of x3 + 5x − 20 fields. What expression would represent the seeds the farmer needs t
Fittoniya [83]

Answer:

Step-by-step explanation:

(3x^2-4x+10)(x^3+5x-20) =3x^5-4x^4+25x^3-80x^2+130x-200

x=1 is not a good value since when you plug it in you get -126 and you can't have a negative number of seeds.
