Hey there! :)

Answer:

-1/3.

Step-by-step explanation:

Find the slope of the line using the slope formula:

m = \frac{\text{rise}}{\text{run}} = (y_2 - y_1)/(x_2 - x_1)

Use two points from the graph and plug them into the equation. We can use the points (0, 3) and (3, 2):

m = (2 - 3)/(3 - 0)

Simplify:

m = -1/3. This is the slope of the line.

Taylor and Abby shared a $55 cash prize in the ratio 2:3. How much money did Taylor get?

Answers

the 2 to 3 ratio means there was 5 equal shares.  because 2 plus 3 is 5

so if you divide 5 into 55 you get 11.  each share is 11.

then multiply 11 by  or 3 (depending on the person) in this case 2 because we want to know about Taylor

2 times 11 is 22.

Taylor got 22 dollars
