Write your answer in standard form with integer coefficients.

1. (-5, 2); m = 2/5

2.(-6, -1); m=-4

how do i do this?

    I would do this. The straight line formula is
    y = mx + b
    m = 2/5 and you want the line to go through the point x=-5 and y = 2; therefore, substitute those values for x and y. I'll let you do the work but I get b = 4 and the equation then looks like this.
    y = (2/5)x + 4. The problem asks for integers so multiply through by 5.
    5y = 2x + 20
    CHECK:
    5(2) = 2(-5) + 20
    10 = -10 + 20
    20 = 20 so it checks.
