The graph below shows the price, y, in dollars, in different number of pounds of dried coffee, x
a. y= x + 10
b. y = 10x
c. y = x + 5
d. y= 5x
first right answer will be brainliest!

D. Y= 5x.

Step-by-step explanation:

For the first coordiantes, it is (2, 10). Then, (4,20). Next, it was (6,30). 2*5=10. 4*5=20. 6*5=30 and so on.

OPTION D.

Step-by-step explanation:

The equation of the line is:

y=mx+b

Where m is the slope and b is the y-intercept.

As you can see in the graph attached, the line intersects y at the origin (0,0), then b=0

Choose a point of the line and solve for m:

Then the equation is:
