hey. Could anyone help me?
Standart form:
y=mx+n where m is slope, and n is y intercept
y=-3x+n
(2,1) has to right for this equation
x=2, y=1
1=-3*2+n
1=-6+n
1+6=-6+6+n
n=7

y - y_{1} = m(x - x_{1}) ; (x,0) - x-intercept, (0,y) - y-intercept.
~~~~~~~~~~~~
y - 1 = -3(x - 2) ----> y - 1 = -3x + 6
y + 3x = 6 + 1
3x + y = 7 -standard form
3x + 0 = 7 ---> x = 7/3 ----> (7/3 , 0) - x-intercept
3*0 + y = 7 ----> y = 7 ----> (0 , 7) - y-intercept
