Write the equation of the line containing the point (3, –2) and having a slope of 2 in slope-intercept form.

Answers

Calculation of b:
y = mx + b
-2 = 2(3) + b
b = -2 - 6
b = -8

So, Equation would be: y = 2x - 8

The amount of postage placed on a first class letter depends on the weight of the letter .

Answers

amount is directly proportional to weight
thus
A = kw               A  =  amount
                           k  = constant      ^    which is price per gram
                           w =  weight

Which relation is a function?

Answers

Of the provided graphs, the second would be the correct answer.

Functions occur when the input only has one possible output (though the output can be recieved through multiple inputs)

The relation shown in the 2nd diagram is a function.  The reason for this is that one and only one y-value is associated with each x-value.  

Note that this is not true of the first diagram.  If x=0, there are two separate y vaues associated: -1 and 2.  This clearly states that the first diagram does not represent a function.

Polygon ABCD will be dilated by a factor of 2 to produce polygon A′B′C′D′. The origin is the center of dilation. Which point will not represent a vertex on polygon A′B′C′D′ ? (­-2, -2) (4, 3) (0, 2) (4, -2)

Answers

Since the origin is the center of dilation then the factor of dilation is 2 so just multiply the coordinate of every vertex by 2. So, the vertices will become A'(-2,-2), B'(0, 2), C'(4, 4) ad D'(4,-2). Therefore,  letter B is the answer.
