PLEASE HELP! The following graph shows the cost c, in dollars, of p pounds of bananas at a local grocery store. Answer all of A, B, and C. A. What does the ordered pair (4, 2.32) represent in this situation?
B. Where can you see the cost per pound of bananas in the graph? What is this amount?
C. Is the relationship shown in the graph a direct variation? How can you tell?

A. The ordered pair (4, 2.32) represents that it costs $2.32 to buy 4 pounds of bananas. B. You can see the cost per pound of bananas, or unit rate, at the point where p = 1, which is (1, 0.58). The unit rate is $0.58 per pound. NOTE: It is hard to tell where the point is exactly so I find a spot I know, like (4,2.32) which they gave us, and then I divide y divided by x to get the unit rate. So I would divide 2.32 by 4 and then I know that the unit rate (price per pound) is $0.58. C. The relationship shown in the graph is a direct variation because the graph is a straight line, or has a constant slope.

a.)

(4, 2.32) shows that for $2.40, you can buy 4 bananas.

b.)

You can see the cost per pound where p=1 on the graph. The point is on around (1,0.6) so it costs $0.60 for one pound of bananas.

c.)

The line on the graph is a direct variation because the slope is consistent and passes through the origin.

I hope this helps! I know that the person above me answered correctly but i just wanted to solve it in my own words to see if it can help also. :) have a nice day!

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
