Answer:
New scale will be
E(-1, -3.5), F(2, -1.5), G(0, 0.5), H(-2, -1). This is one-half the original scale
Step-by-step explanation:
The question is incomplete. Here is the complete question.
"Given the Quadrilateral with vertices E(-2,-7),F(4,-3),G(0,1),and H(-4,-2), find the coordinates of the image after a dilation having a scale factor of 0.5."
Dilation factor is the same as scale of 1/2 i.e 1:2. Scale of 1:2 means that the quadrilateral has been reduced by one-half. We need to know the new vertices of the quadrilateral after being reduced by one-half.
Given the original axis before dilation
E (x1, y1) = E(-2, -7)
F (x2, y2) = F(4, -3)
G (x3, y3) = G(0, 1)
H (x4, y4) = H(-4, -2)
After dilation by scale factor of 0.5, the axis will result into one half of its original scale as shown:
E (0.5x1, 0.5y1) = E(-2/2, -7/2)
F (0.5x2, 0.5y2) = F(4/2, -3/2)
G (0.5x3, 0.5y3) = G(0/2, 1/2)
H (0.5x4, 0.5y4) = H(-4/2, -2/2)
New scale will be:
E(-1, -3.5), F(2, -1.5), G(0, 0.5), H(-2, -1)

Answer:
y = 2/3x - 7
Explanation:
First we must turn 3x + 2y = 6 to slope intercept form. In order to do this first subtract 3x on both sides of the equal sign, so we can get 2y by its self. Now we're left with 2y = -3x + 6 .
Next divide 2 from both sides to get y by its self. Now you got y = -3/2x + 3 (since 6 can be divided by 2 it's a 3 now) <u>Look above to see y= -3/2x +3 graphed</u>. ⤴⤴⤴
To find out the other equation we first need to know what its y-intercept is, and luckily for us we've already been given -3.

This is a bit lengthy, but I hope you get it :)
