the line is solid so we have either ≤ or ≥
find the equation of the line
ok, a y intercept if -1
sllope=rise/run=3/1=3
y=mx+b
m=slope
b=y intercept
y=3x-1 is the equaton
now find if it's y≥3x-1 or y≤3x-1
test a point
we see (0,0) Is not in in it
test it in y≥3x-1
0≥3(0)-1
0≥-1
false,
so this is the equation because (0,0) is not a valid solution for this equation
answer is y≥3x-1
