The answer is -4 because -4 times -3 equals -12
The gradient formula is (y2-y1)/(x2-x1) aka rise/run, where by (x1,y1) and (x2,y2) are two points on the line.
In this case, the gradient
= -5-(-2))/(2-(-2))
= -3/4
Let the number of hours she work be n
So the equation will be
P = 9n
(y2-y1)/(x2-x1)
=(5-3)/(3-2)
=2/1
=2
so the slope is 2
hope this helps !
Because you are told the two are similar, find the ratio of them.
Side AB = ft and side EF is 25 feet.
This means the larger rectangle is 5 times larger ( 25 /5 = 5).
Area is in square units, so square the ratio: 5^2 = 25
The area of the larger rectangle is 25 times the area of the smaller one.
Area = 35 x 25 = 875 ft^2
