we are given
where
price p( in dollars) of a new smartphone
t is the number of months since January
now, we can solve for t
step-1:
Add both sides by 4t^2
step-2:
Subtract both sides by p
step-3:
divide both sides by 4
step-4:
Take sqrt both sides
so, we get

Answer:
y - 2 = - (x - 7)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 4 ← is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
The equation of a line in point- slope form is
y - b = m(x - a)
m is the slope and (a, b) a point on the line
Here m = - and (a, b) = (7, 2), thus
y - 2 = - (x - 7) ← equation of perpendicular line
