Look at the table of x and 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) 5x-3

(1,3), (2,7), and (3,11):

Let's find the slope m between (1,3) and (2,7)

Slope = Rise / Run

m = (7-3) / (1)

m = 4.

Our equation y=mx + b has a slope of 4. Since C is the only option that satisfies this, we already know the answer, but let's find the y-intercept.

y = mx + b. Plug in 4 for m, and the first coordinate (1,3) for x and y

3 = 4 (1) + b Subtract 4 from both sides

b = - 1

Our function is y = 4x - 1

Answer is C) y=4x-1
