What is the y-intercept of the line (-10,-4) (-2,1) ?

The slope of the line will be

(1+4)/(-2+10) = 5/8

The slope intersect form will be

Y=(5/8)x + b

plugging any one of the two points we have

1=(5/8)(-2) + b

b=1+(5/4)

b= 9/4

Check

-4=(5/8)(-10) +(9/4)

-4 = -4

Check!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
