Answer:
the formula: Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
how to find the slope intercept:
- Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
- Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Step-by-step explanation:
Answer:
C. They are similar because their corresponding angles are congruent and their corresponding side lengths are proportional.
C or A for x =6. ……………………………….
We have been four choices of dilation. We are asked to choose the option that represents reduction.
We know that a dilation changes the size of the image. The scale factor determines how much larger or smaller the image will be after dilation.
When scale factor is 1, then both image and pre-image will be same.
When the scale factor is greater than 1, then image will be larger than pre-image or original image.
When the scale factor is less than 1, then image will be smaller than pre-image or original image.
Upon looking at our given choices, we can see that option F, G and J has scale factor greater than 1, so these will be enlargement.
The scale factor is option H is 0.2, which is less than 1. Therefore, the dilation
is a reduction and option H is the correct choice.
