The information we have is:
So we can find that two coordinates are ( -2,-8 ) and ( 3,7 ) so we can use the equation to find the slope so:
So the equation now will be:
So we can replace one coordinate to find b so:
So the final equation is:
Write a percent that has a value between the two decimals 0.4 and 0.5

Answer:
Option B
Step-by-step explanation:
We are given the following system of equations -
Now by Cramer's Rule, we would first write down the matrix of the coefficients , replacing each column with the answer column -
,
Replace each column of the coefficients shown at the top, with the answer column at the bottom respectively -
Now solve through Cramer's Rule -
x = Dx / D = - 6,
y = Dy / D = - 1,
z = Dz / D = 1
<u><em>Solution = ( - 6, - 1, 1 ) = Option B</em></u>
