Answer:
B. y = -2/3x + 12
Step-by-step explanation:
Formula to find the slope when given two points on a line:
<u>y</u><u>2</u><u> </u><u>-</u><u> </u><u>y</u><u>1</u>
x2 - x1
Substitute the two given points (6, 8) (9, 6):
<u>6</u><u> </u><u>-</u><u> </u><u>8</u>
9 - 6
Slope = -2/3x
We found the slope! And the answer choices already gave us one y-intercept, which is 12. The last thing we do is we form an equation with the information we solved and that was given to us.
y = slope (x) + y-intercept
y = -2/3x + 12
The answer choice that matches this equation is B.
In conclusion, the equation that best estimates the line of best fit shown above is answer choice B.
Answer:
parallel
Step-by-step explanation:
x=4 and x=-6 are both vertical lines
Vertical lines are parallel (they both have undefined slopes)
Answer:
$512
Step-by-step explanation:
Charges at the first hotel are ...
4(168 -40) = 4(128) = 512
Charges at the second hotel are ...
(4-1)(185) = 3(185) = 555
The first hotel offers the better rate: $512 for four nights.
