Answer:
1. (AB) y = 2/3x + -4
Step-by-step explanation:
Formula - y = m(x) + (y-intercept)
m = rise / run
"run = horizontal (left and right)
rise = vertical (up and down)"
the y intercept is always going to be where y is 0 at. (x, y) you will use your x to determine the intercept
So lets use your first question as an example
1. (AB) y = m(x) + (y-int)
y = m(x) + (-4)
the point goes to the right 6 points and goes up 4 points (rise / run)
y = 4/6(x) + (-4)
You can round up the fraction to 2/3
y = 2/3(x) + -4
Its 4 plus i square root of eleven
Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratio of corresponding sides are equal
(a)
= 
, substitute values
= 
( cross- multiply )
13.23AB = 111.132 ( divide both sides by 13.23 )
AB = 8.4
(b)
= 
, substitute values
= 
( cross- multiply )
6.3DF = 54.243 ( divide both sides by 6.3 )
DF = 8.61
Put it as a fraction which is 15/20. Then divide so it would be 0.75
