Answer:
8 = 3x - 4y
or y = (3/4)x - 2
Step-by-step explanation:
(4,1) and (0, -2) are the two points I see.
slope = (1 -(-2))/(4 - 0) = 3/4
y-int: -2
y = (3/4)x - 2
or 2 = (3/4)x - y
8 = 3x - 4y
Answer:
102
Step-by-step explanation:
Perimiter is where you add all the sides and a rectangle has four sides.
28/4=7
But the length is 4m longer then the width so, 7+4=11 but if we do 11+11+7+7= 36. But that is not the perimeter so 7-4=3
And if we do 11+11+3+3=28!
Therefore the length of the rectangle is 11m and the width is 3m
To find the area we just do 11•3=33
The only reason this is long is because i explained and put it into detail but its pretty simple and short once you get the hang of it :)
