Equation for ( 6, 13) ( 7900, 5 )

tia_tia [17]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

$y=mx+b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following points through which the line passes:

$(x_ {1}, y_ {1}) :( 6,13)\\(x_ {2}, y_ {2}): (7900,5)$

We find the slope of the line:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {5-13} {7900-6} = \frac {-8} {7894} = - \frac {4} {3947}$

Thus, the equation of the line is of the form:

$y = - \frac {4} {3947} x + b$

We substitute one of the points and find b:

$13 = - \frac {4} {3947} (6) + b\\13 = - \frac {24} {3947} + b\\13+ \frac {24} {3947} = b\\b = \frac {51335} {3947}$

Finally, the equation is:

$y = - \frac {4} {3947} x + \frac {51335} {3947}$

Answer:

$y = - \frac {4} {3947} x + \frac {51335} {3947}$

NO LINKS <br> what is the answer??

Alex787 [66]

Answer:

5625 bald eagles

Step-by-step explanation:

Given

$y = 312.5x + 1562.5$

Required

Predict the numbers in 1998

First, we calculate the value of x

$x = 1998 - 1985$ ---- years since 1985

$x = 13$

So, we have:

$y = 312.5x + 1562.5$

$y = 312.5*13 + 1562.5$

$y = 4062.5 + 1562.5$

$y = 5625$
