    Answer:

    19y – 34x = 376

    Step-by-step explanation:

    We are to write the linear equation of a line passing through the points

    (-20, -16), (-1, 18)

    Using the points slope form of the equation expressed as;

    y-y0 = m(x-x0)

    m is the slope

    (x0,y0) is any point on the line

    m = y2-y1/x2-x1

    m = 18-(-16)/-1-(-20)

    m = 18+16/-1+20

    m = 34/19

    Substitute the slope m =34/19 and the point (-1, 18) into the expression given

    y- 18 =34/19(x-(-1))

    19(y-18) = 34(x+1)

    19y – 342 = 34x+34

    19y-34x = 34+342

    19y – 34x = 376

    Hence the required equation is 19y – 34x = 376
