Find the equation of the line shown below...
vovangra [49]

Answer:

y = -1/4x+2

Step-by-step explanation:

We can find the slope by finding two points on the line, and doing (y1-y2) ÷ (x1-x2). The two points I chose were (0,2), and (4,1). We can plug this into the equation to get (2-1) ÷ (0-4), to get -1/4, which is our slope. We can see on the graph, that the line intersects with the y axis when the y coordinate is 2, making the y-int 2.

Which list of numbers is in order from least to greatest?<br> 3/6 3/10 3/7
lapo4ka [179]
The list of numbers from least to greatest is 

3/10 , 3/7, 3/6

This is because the numerator stays the same across all three of these fractions.  However, the denominator is changing, and this proves to be a large difference.  

Think about it this way: If you cut a pie into ten pieces, then those slices are going to be smaller than if you cut the pie into seven or six pieces.
