The linear model of this case takes the form:

y = a(x-b) + k

<span>The cost of having a package delivered has a base fee of $9.70
this is "k" >>>>>  k=9.7 (fixed amount of fee)

THEN

</span>
<span>Every pound over 5 lbs cost an additional $0.46 per pound

that means: 0.46(x-5)
in other words, if the package weighs foe example 9 pounds, then 9-5=4, it will cost 0.46*4 for these 4 extra pounds

Finally we have the linear form of this: C = 0.46 (W - 5) + 9.7

What is the equation for y=3x+5
VLD [36.1K]

The graph of  y = -3x+5

Step 1: Since the  y - intercept is 5, plot the point (0,5).

Step 2: Since the slope is -3, move 1 unit to the right and 3 units down, so plot the point (1,2).

Step 3: Connect those points by a straight line.

Determine the equation of a line through the point (3,-4) that is perpendicular to the line y=3x+7
Lana71 [14]

Answer:

y = - \frac{1}{3} x - 3

Step-by-step explanation:

The equation of a line in slope- intercept fprm is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 7 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

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{3}, thus

y = - \frac{1}{3} x + c ← is the partial equation of the perpendicular line

To find c substitute (3, - 4) into the partial equation

- 4 = - 1 + c ⇒ c = - 4 + 1 = - 3

y = - \frac{1}{3} x - 3 ← equation of perpendicular line
