Question

what is an equation in slope-intercept form for the line that passes through the points
(1,-3) and (3,1)?

I got y = 2x + 5

Answer 1

The 5 should be negative

Answer 2

That's what I thought, but when I looked at the answer choices, none of them were negative 5's.

These were the choices:
y = 3x + 1
y = x – 3
y = 2x + 5
y = 2x – 5

Answer 3

The last one is right

Answer 4

Okay, I thought since the slope intercept form equation was y = mx + b, that it had to be a addition sign.

Answer 5

Thats just the form you need to have, the b could be positive or negative it just depends on what line you're doing

Thanks.
