Question

What is the equation of the line that passes through (4, -1) and (-2, 3)?

Answer 1

We need to find the slope, and the y intercept.
Slope:
y1 - y2 over x1 - x2

-1 - 3 over 4 + 2
-4 over 6

So our slope is:
-4/6x

Answer 2

So we have:
y = -4/6x + b

Answer 3

we need the y intercept, or b

Answer 4

the y intercept is the point where x = 0, try and find it using the slope.

Answer 5

Whats the answer B?
