Answer 1

Answer: Choice C
The equation is y = 4x-3

---------------------------------------

How I got that answer:

The first row has x = 0 and y = -3
So the answer is narrowed to either A or C. These answer choices have a y intercept of -3. Choices B and D have a y intercept of 3.

We need the slope now. Pick any two points from the table. I'm going to pick (0,-3) and (2,5) from the first two rows.

Slope formula:
m = (y2-y1)/(x2-x1)
m = (5-(-3))/(2-0)
m = (5+3)/(2-0)
m = 8/2
m = 4

The slope is 4, so the equation is y = 4x-3
That's why the answer is choice C
(we can rule out choice A as that slope is 1)
