Answer:
y=x-5
Step-by-step explanation:
For this, use point-slope formula, which is (y-y1)=k(x-x1), in which k is slope.
Now, substitute in your values. (y-2)=1(x-7)
Then, since you got y-2=x-7, add 2 to both sides.
You get y=x-5
Let there were total x people at the conference
so 32%of x is 216
32/100×x=216
x=216×100/32
x=675
So total people present at the conference were 675
