Write an equation in slope-intercept form (0,2) (7,-1)

Mathematics
1 answer:
maksim [4K]3 years ago

Answer:

y=-3/7x+2

Step-by-step explanation:

first formula (Slope): y2-y1/x2-x1

-1-2/7-0= -3/7

second formula (point slope): y-y1=m(x-x1)

y-2=-3/7(x-0)

(distribute the -3/7)

y-2=-3/7x-0

(add 2 to both sides)

y=-3/7x+2

spin [16.1K]

Answer:

The statement is incorrect because an inverse relationship between y and x would imply that the graph would be a downward curved graph whose slope changes rather than linear which has constant slope  (see image).

Best to express this situation as:
There is a linear relationship between y and x with a negative constant slope. The keyword here is constant since the slope is the same in a linear relationship

Step-by-step explanation:

An inverse relationship exists between y and x when y is proportional to the reciprocal of y

This would be expressed in the form y ∝ \frac{1}{x}

As x decreases , y increases or vice-versa. It is often expressed in equation form as y=\frac{k}{x}  or y = kx^{-1}   where k is a constant and  whose graph is curved in nature. The slope is changing for the range of x values not constant as would be the case for a linear graph

All we can say about the data is that there is a linear relationship between y and x  with a negative constant slope

How long does it take $450 to double at simple interest rate of 14%
umka2103 [35]
A = P(1+rt)
A (Future) = 450(2) = 900
P (Principal) = 450
R (Rate) = 14% = .14
T (Time) = Unknown

Create the equation:
900=450(1+.14t)

Distribute the 450:
900=450 + 450(.14t)

Multiply the 450(.14t)
900=450 + 63t

Subtract the 450:
450 = 63t

Divide by 63:
t=7.142857

Answer:
It will take 7.1 years.
