Question

Look at the table of values below. x y 1 3 2 7 3 11 Which equation is represented by the table? A. y = 2x + 1 B. y = 3x + 2 C. y = 4x − 1 D. y = 5x − 3 <---- its a plato question

Answer 1

C. y = 4x − 1

Step-by-step explanation:

x y

1 3

2 7

3 11

We can find the slope

m = (y2-y1)/(x2-x1)

= (11-7)/(3-2)

= 4/1

The slope is 4

The only equation with a slope of 4 is

y = 4x − 1

Check a point

(1,3)

y = (4)*1 -1

y=3

Checks so this works
