Can someone assist me in the right direction with this question?

Find an equation of the line containing the given pair of points. (-5,-6) (1,-3)
The equation needs to be in slope intercept form.

Thanks.

  • Math - ,

    m=y2-y1/x2-x1
    =(-3)-(-6)/1-(-5)
    =3/6
    =1/2

    y=mx+b
    y=1/2x+b

    now use either of the points to solve for b

    -3=1/2(1)+b
    -3-1/2=b
    2.5=b

    so

    y=0.5x+2.5

  • Math - ,

    -3 - 1/2 = -7/2 not 2.5

    so y = (1/2)x - 7/2
