m = (-1 - 4) /(2-3) = -5/-1 = 5
slope = 5
passing (3, 4)
y = mx + b
4 = 5(3) + b
4 = 15 + b
4 -15 = b
-11 = b or b = -11
answer:
equation
y = 5x - 11
Answer:
The playground covers
of a square mile
Step-by-step explanation:
The playground is a rectangular ground. The area of a rectangle is given by legth * width, hence,
The area of the playground is length * width
Area =
sq. mi
Hence the playground cover
of a square mile
Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
