Question

What is the y intercept of the table

-1

1.5

-3

1

Answer 1

-3

Explanation:

Your slope is 2:1 or 2 y's per 1 x...

the y-intercept is at x = 0...

you must subtract 1 from x = 1 to get x = 0...

therefore, you must subtract 2 from y = -1...

-1 - (-2) = -3

Answer 2

-3

Explanation:

this is a linear equation, it goes up by 2, y intercept is when x=0 so take away 2 from -1 which is -3
