The graph below shows a line segment mn: which of the following equations best represents the line segment mn?
y = −3x + 2
y = −2x + 1
y = −3x − 2
y = −2x − 1

D.

Step-by-step explanation:

We have been given a line on coordinate plane. We are asked to find the equation of our given line.

First of all, we will find slope of our given line using points and in slope formula.

, where,

= Difference between two y-coordinates,

= Difference between two x-coordinates of same y-coordinates.

Upon substituting our given values in slope formula, we will get:

Now, we will use slope-intercept form of equation , where,

m = Slope of line,

b = The y-intercept.

Upon looking at our given graph, we can see that y-intercept is .

Therefore our required equation would be and option D is the correct choice.

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
