Write the equation of a line in slope intercept form that has a slope of -2 and passes through the point (-1,8)

y = -2x + 6

Step-by-step explanation:

m=slope

b=y-intercept

(x, y) = (-1, 8)

y = mx + b

8 = -2(-1) + b

8 = 2 + b

b = 8-2

b = 6

y intercept = (0, 6)

y = -2x + 6

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
