From the graph let's take the points as the ordered pairs:

(3, 3), (4, 5), and (5, 7)

Given the equation:

y = 2x - 3

Let's verify for all points, if the equation matches the graph:

a) (x, y) ==> (3, 3)

Substitute 3 for x and 3 for y in the equation

y = 2x - 3

3 = 3(3) - 3

3 = 6 - 3

3 = 3

b) (x, y) ==> (4, 5)

Substitute 4 for x and 5 for y:

y = 2x - 3

5 = 2(4) - 3

5 = 8 - 3

5 = 5

c) (x, y) ==> (5, 7)

Substitute 5 for x and 7 for y:

y = 2x - 3

7 = 5(2) - 3

7 = 10 - 3

7 = 7

Since the left side equals the right side of the equation, the equation

y=2x-3 matches the graph.

Therefore, Jayla is correct.
