Answer:


Step-by-step explanation:

By triangle theorem for similarity we have

AC||DE if and only if

the ratios

\frac{AD}{BD}=\frac{CE}{EB}

Option I:

Here we find the ratios are equal to 1/2

Hence parallel

OPtion 2:

Here we get both ratios equal to 2/3 Hence parallel

Option 3:

Here we get I ratio =2/5 and II ratio =4/7

Since the two are not equal we get not parallel

Which of the following is an equation of the line that crosses through (-3,4) and (3,6)?
Mama L [17]

Answer:

y=(1/3)x+5

Step-by-step explanation:

Slope-intercept: y=mx+b

y=(1/3)x+b

plug in one of the points (3,6)

6=(1/3)(3)+b

6=1+b    5=b
