Equation stuff...

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.
