Answer:
y = mx + b
mx = slope
b = y intercept
mx = 2/1
Rise 2, Run 1 = slope
y = 2/1x + b
b = (0,2)
y = 2/1x + 2
Answer:
The scale factor is
Step-by-step explanation:
Line segmentAB has vertices A(−3, 4) and B(1, −2) .
A dilation, centered at the origin, is applied to AB. The image has vertices
A'(-1,4/3) and B′(1/3, −2/3) .
We know the rule for dilation by scale factor of k, is
This means that;
But we know, A' has coordinates (-1,4/3)
This means that
We could also compare:
4k=4/3
Which gives
k=⅓
