Answer:
Scale factor, K = -1/4
Step-by-step explanation:
Dilation of any image changes its size and the shape remains same.
The scale factor is the ratio of dilated image to original image.
Dilation rule: (x, y) → (kx, ky), where k is the scale factor.
It means k = x₂/x₁ or y₂/y₁
K = -5/20 = -1/4 or K = -4/16 = -1/4.
<u>The negative value of scale factor (K) indicates dilations with 180 degree rotation of the dilated image.</u>
Hence the scale factor is K = -1/4.
Slope intercept form
y = mx + b:
10 = 7x + 3
y = 10
slope (m) = 7
b = 3
standard form:
Ax + By + C:
7x + 10y + 3
A = 7
B = 10
C = 3
hope this helps
