I would say 2. As the line of best fit is supposed to represent the average of all the data points. It's not nessecarily needed to go through every point.
Answer:
Start with y=mx+b since it is perpindicular to the slope of -3/4 the new slope is 3/4. so now we have m=4/3 next we subsitute known values in (0,-1). We multiply 0 by 3 next we have -1=0+b so be has to be -1 so your awnser is
y=4/3-1
It will take you 3/4 of an hour, or 45 minutes to paint 1 wall.

Step-by-step explanation:
Since Veronica buys 2 games for $30.00 each and a game controller for $19.59. The total cost to be paid will be:
= (2 × $30.00) + $19.59
= $60.00 + $19.59
= $79.59
Since Veronica lives in San Jose, California, where sales tax is 9.25%, the sales tax will be:
= 9.25% × $79.59
= 0.0925 × $79.59
= $7.36
Total amount paid = $79.59 + $7.36 = $86.95
Answer:
700.4 cm
Step-by-step explanation:
Use a proportion.
Let x be the vertical distance for the 700 cm pipe.
1 cm is to 30 cm as x cm is to 700 cm
1/30 = x/700
30x = 1 * 700
30x = 700
3x = 70
x = 70/3
Now we need l. We have a right triangle with legs measuring 70/3 cm and 700 cm, and we are looking for the hypotenuse l.
a^2 + b^2 = c^2
(70/3)^2 + 700^2 = c^2
c^2 = 4900/9 + 490000
c = 700.4
l = 700.4 cm
