Answer:
Step-by-step explanation:
(19+2)/7
4+ x(5)=8.50 (we use 5 hours since the 1st hour is included in the 4 dollars)
4+5x=8.5 subtract 4 from each side
5x = 4.5 divide each side by 5
x=.9
x=$0.90
The points are not collinear.
Solution:
Let A, B and C be (3, -10), (-2, -7) and (0, -5).
<em>If slopes of any two points are same, then the points are collinear.</em>
Slope formula:
<u>Slope of AB:</u>
<u>Slope of BC:</u>
<u>Slope of CA:</u>
Slope of AB ≠ Slope of BC ≠ Slope of AC
Therefore the points are not collinear.
The 3rd one. It is the line that shows the average of most of the points since it’s more in the middle.
