Find the equation (in slope=intercept form) of the line through the points(-1, -5) and (1,1)

Answer 1

(-1,-5) and (1,1) have a line through them with slope = (1+5)/(1+1) = 6/2 = 3

y-1 = 3(x-1) = 3x -3

y= 3x-2

is the equation through the points, in slope intercept form, slope =3, y intercept = -2

check the answer, plug in the two points

1=3(1)-2=3-2

-5=3(-1)-2=-3-2
