Complete the equation of the line through ( − 1 0 , − 7 ) (−10,−7) and ( − 5 , − 9 ) (−5,−9).

The point-slope form:

The formula of a slope:

We have the points (-10, -7) and (-5, -9). Substitute:

   point-slope form

     use distributive property

    subtract 7 from both sides

     slope-intercept form

          multiply both sides by 5

     add 2x to both sides

     standard form

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
