Given:
Vertices of a triangular garden:
A(4,2)
B(2,4)
C(6,4)
Scale factor = 0.5
Find the distance between points:
d = √(x2-x1)^2 + (y2-y1)^2
dAB = 2√2
dBC = 4
dCA = 2√2
A similarly shaped garden is to be created using the scale factor, 0.5:
A' = 2√2 / 0.5 = 4√2
B' = 4 / 0.5 = 8
C' = 2√2 / 0.5 = 4√2
You can think of this as ratios
1 :8
3:24
2.5 : 20
8:64
12:96
4.5:36
Answer:
a=4
Step-by-step explanation:
ax − 4 = 2y
We need to get the equation is slope intercept form y= mx+b.
Lets solve for y
Divide each side by 2
a/2 x - 4/2 = 2y/2
a/2 x -2 = y
or y=a/2 x -2
The slope is a/2 and the y intercept is -2
We want a slope of 2 so a/2 =2
a/2=2
Multiply each side by 2
a/2 * 2 =2*2
a =4
