A line passes through the points (-10, -4) and (-1,2) what is the y- intercept

Question

solomonzelman · Answer

first find the slope

y1 - y2                      -4 - 2                      -6
------      --->      ------      --->      ----   = 2/3
x1 - x2                    -10 - -1                     -9

so, you know so far
y=(2/3)x+b


the y-intercept is still unknown, plug any of the 2 points to find it.

y=(2/3)x+b

lets pick the first points,   (-1,2) 

(2)=(2/3)(-1)+b
2=-2/3+b
2+2/3=b
b=2, 2/3

So the y-intercept is 2, 2/3 or 8/3

Solomon would it be (,0 8/3) 0r (8/3,0)

I see what you are asking, y-intercept is at x=0 and intersects the y axis.
y-intercept should look like  ( 0 , y-intercept )
