Answer:

y = -1/2 x - 3.5

Step-by-step explanation:

y = mx+ b

m is the slope of the line

m = -1/2

b is the y-intercept

b = -3.5

Answer:

y=(-1/2)x-3.5

Step-by-step explanation:

Using the equation (rise/run) with the two marked points, we find that the slope is (1/-2), or -1/2.

The y-intercept, as seen in the graph, is -3.5.

Once you plug the slop and y-intercept into y=mx+b, you get your equation: y=(-1/2)x-3.5

To check your answer, swap x and y out for values of a point on the line. With the point (1, -4)..:

-4=(-1/2)1-3.5

-4=(-1/2)-3.5

-4=-4

A farmer Has 900 yards of fencing to enclose a rectangular pasture for her goats. Since one side of the pasture borders a river,

Answer:

Length, l=450 yards

Width, b=225 yards

Step-by-step explanation:

Let the long side be x and since the length is twice the width, then the width is half of that length hence 0.5x. Since we only have three parts to fence as one long side doesn't require fencing, then the perimeter will be given by x+0.5x+0.5x=2x=900 yards

X=900/2=450 yards for long side.

The short side is 0.5x hence 0.5*450=225 yards

In conclusion, the long side is 450 yards while short side is 225 yards.

Write the expression as a whole number with a negative exponent. Do not evaluate the expression.

WINSTONCH [101]

Answer: $\frac{1}{3^6}=3^{-6}$

Explanation: Denominators of a fraction can be equivalently written as their value to the power of negative 1. In this case the denominator expression itself has an exponent of 6, which taken to the power of negative one becomes -6:

$\frac{1}{3^6}=(3^6)^{-1}=3^{6(-1)}=3^{-6}$
