Step-by-step explanation:
Slope intercept form of an equation is written as;
y=mx+b where m is the slope of the line and b is the y-intercept
Given points (3,19) and (8,42) find m as;
m=Δy/Δx
Δy=42-19=23
Δx=8-3=5
m=23/5
Finding the equation of the line where m=23/5, point (3,19) and (x,y)
m=Δy/Δx
23/5=y-19/x-3
cross product
23(x-3) = 5(y-19)
23x-69=5y-95
23x=5y-95+69
23x=5y-26
23x+26=5y
23x/5 +26/5 =5y/5
23/5 x +26/5 =y
⇒⇒ y=23/5x +26/5

Answer:
Step-by-step explanation:
A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.
When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".
When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".
In this case you know that the triangle ABC was dilated by this scale factor:
With the origin as the center of dilation.
Since:
It is a Reduction.
You can identify that the vertices of the triangle ABC are:
So you need to multiply the coordinates of each vertex of the triangle ABC by , in order to get the coordinates of the triangle A'B'C. Then, you get:
