Question

write an equation of the line that passes through the points (-1,4) and (-5,2)

Answer 1

suppose first point is (x1,y1) and second point is(x2,y2)
then formula
(y-y1)/(y2-y1)=(x-x1)/(x2-x1)

Answer 2

now u can solve

Answer 3

y= x/2 + 9/2

Answer 4

slope = (-1) x coefficient/y coefficient
now put in formula:
(y-y1)=slope(x-x1)
