Write the following system of equations as an augmented matrix. ⎧⎩⎨⎪⎪b+3c−3b−8c−b−3c+s=350=300=250

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

$649.60
