Answer:

y = -1/5 + 7

Step-by-step explanation:

Substitute the point (1,2) for the x and the y in the equation, set the 4 to b since we are solving for b.

2 = -5(1) + b now solve for b

2 = -5 + b

+5 +5

7 = b

we know that the slope must be the reciprocal for it to be perpendicular

y = -1/5 + 7 add b (7) to the equation and change the reciprocal

Fill in the Blanks

Answer: This would fill 4 and 4/9 containers.

Explanation:

Since we have given that

Quantity of walnuts in a container is given by

$6\frac{2}{3}=\frac{20}{3}\ pounds$

Quantity of walnuts which divided equally into containers is given by

$1\frac{1}{2}=\frac{3}{2}\ pounds$

Now, number of containers they would fill is given by

$\frac{\frac{20}{3}}{\frac{3}{2}}=\frac{20\times 2}{3\times 3}=\frac{40}{9}$

When we change it into mixed fractions we get,

$\frac{40}{9}=4\frac{4}{9}$

So, blank will be filled with '4'.
