Which linear inequality is represented by the graph?
aalyn [17]

Answer:

y ≤ 1/3 x - 1.3.

Step-by-step explanation:

First find the equation of the line:

The slope = (-0.3 - (-1.3) / (3 - 0).

= 1/3 so the equation is y = 1/3x + b where b is a constant.

b is the y-intercept which is the value of y when x  = 0 . We see that it is -1.3 ( from the point 0, -1.3).

Since the line is continuous and the shading is below this line the inequality sign is 'less than or equal to',  ≤.

I spent 25 Points, PLEASE HELP! In a graph, x represents the number of months since a business opened, and y represents the tota
vlada-n [284]
First find the slope.  m=(y2-y1)/(x2-x1)

m=(4225-1990)/(5-2)=745,

m is the slope, this represents the amount of money earned each month that the business operates.

so far we have:

y=745x+b, using any point we can solve for b, I'll use (2,1990)

1990=745(2)+b

1990=1490+b

500=b

b is the y-intercept which is $500, it represents the amount of moeny that the business started with.
