Question

Which function shows a fabric with a price of $1.25 per square yard? A table showing Price of Fleece with five columns and two rows. The first row, Square Yards, has the entries, 1, 2, 3, 4. The second row, Price, has the entries, $1.25, $2.00, $2.75, $3.50. A table showing Price of Fleece with five columns and two rows. The first row, Square Yards, has the entries, 1, 2, 3, 4. The second row, Price, has the entries, $0.25, $1.25, $2.25, $3.25. A coordinate plane showing Price of Fleece. The x-axis shows Number of Square Yards and the y-axis shows Price in dollars. A line starts at (0, 0) and passes through (5, 4) and ends (10, 8). A coordinate plane showing Price of Fleece. The x-axis shows Number of Square Yards and the y-axis shows Price in dollars. A line starts at (0, 0) and passes through (4, 5) and ends (8, 10).

Answer 1

D) A coordinate plane showing Price of Fleece. The x-axis shows Number of Square Yards and the y-axis shows Price in dollars. A line starts at (0, 0) and passes through (4, 5) and ends (8, 10).

Explanation:

Rise/Run

y2 - y1 = ? | x2 - x1 =? ?\?

Slope of Table A) $2.00 - $1.25 = 0.75 | 2 - 1 = 1 so 0.75/1 = 0.75❌

Slope of Table B) $1.25 - $0.25 = $0.25 | 2 - 1 = 1 so 0.25/1= 0.25❌

Slope of Graph C) On a graph rise/run (more easier) 4/5=0.8❌

Slope of Graph D) On a graph rise/run (more easier) 5/4= 1.25 ✔

Answer 2

Answer D is correct

Explanation:

1: (1, 1.25) (2, 2)

So you have your first problem, your first number is x1 while your next number in the first set of parenthesis is y1. Your next set of parenthesis will be x2 and y2 like this:

x1 y1 x2 y2

(1, 1.25) (2, 2)

Then you set up a equation like this!

x2-x1

-------Divided

y2-y1

so we now plug in the numbers and get this

2-1.25 = 0.75

--------- ---- or 0.75 BUT not 1.25 like we need!

2-1 = 1
