Step-by-step explanation:
Let's pick two points on the line: and
Let's calculate the slope of this line using these points:
With this value of the slope, we can write the general slope-intercept form of the equation as
To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:
Therefore, the slope-intercept form of the equation is
First, note that Then use the formula for the sum of perfect cubes:
Therefore,
The quadratic trinomial couldn't be factored anymore, so the expression
has two factors
and
Answer: correct choice is A.
Answer:
It is, indeed, a reduction. But, the scale factor of the dilation should be a fraction instead of a whole number, since the shape has shrunk.
Instead of , it should be
. That would make it (4 - 2) / (8 - 4) = 2 / 4 = 1/2.
Hope this helps!
