Answer:

y=-4x-2

Step-by-step explanation:

the slope intercept form of an equation is y=mx+b, where m is the slope and b is the y intercept. plugging in -4 as the slope, m and -2 as the y-intercept, b, we get the equation y=-4x-2

Arturiano [62]

For this case, we must find the equation of the line.
The generic equation of the line is:
$y-yo = m (x-xo)
$
The slope of the line is:
$m = \frac{y2-y1}{x2-x1}$
Substituting values we have:
$m = \frac{15-12}{2-0}$
Rewriting:
$m = \frac{3}{2}$
$m = 1.5$
We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:
$y-12 = 1.5 (x-0)$
Rewriting the equation:
$y= 1.5x+12$
For 20 visits, we evaluate the equation when x = 20.
We have then:
$y= 1.5(20)+12$
$y= 30+12$
$y= 42$
Answer:
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits
