If the simple interest on $6,000 for 9 years is $4,320, then what is the interest rate? The rate is ?

6.48%

Step-by-step explanation:

the rule of the simple interest is:

I=PRT

but here we want the rate, and we have I and P and T

so put the rate on 1 side, and all the given numbers in other side

the rule will be like this:

R=I/PT

R=4320/6000×9

R=6.48%

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
