Answer:

y = 0.5x + 5

Step-by-step explanation:

Use the slope formula to find the slope of a line given the coordinates of two points on the line.

The slope formula is:

m = \frac{y{2}-y{1}  }{x{2}- x{1} } = \frac{y}{x}

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Now let's fill in the formula with the points,

m = \frac{8-4}{9-7}

Solve,

⇒ Y = 9 – 7 = 2

⇒ X = 8 – 4 = 4

m = \frac{8-4}{9-7} = \frac{2}{4}

Simplify,

⇒ \frac{2}{4}=\frac{1}{2}=0.5

Therefore, the Equation of the line is y = 0.5x + 5.

What is the future value of $845 a year for seven years at an interest rate of 11.3 percent? $6,683.95 $6,075.69 $8,343.51 $8,00
k0ka [10]
The future value of cash whose initial value is $845, at the rate of 11.3% for 7 years will be calculated using the compound interest rate, that is:
A=p(1+r/100)^n
where:
A=future amount
r=rate=11.3%=0.113
time=7 years
thus the future value of our cash will be:
A=845(1+0.113)^7
A=845(1.113)^7
A=$1,787.82

dlinn [17]

Answer:

-1 to 1

Step-by-step explanation:

The correlation Coefficient gives the degree of relationship between two variables while also giving an hint about the type of relationship between them, (positive or negative). Correlation Coefficient could take any value bwuqwen - 1 and 1. With values closer to - 1 or 1 indicating a strong relationship between the variables, Coefficient of 0 means no relationship and a negative value means negative relationship while a positive value plies a positive relationship.
