SOMEONE HALP ME

This I am not so sure though but might be correct but what the heck xD

Step-by-step explanation:

2)

There are three points labelled

The points whose (x , y) values represent the group reaching its fundraising goal would be B(180,21) as its on the line which means it satisfies the equation. The other points A and B are anomalies which don't lie on the line and thus don't satisfy the equation. So 180 tickets were sold during 21 hours of rental thus reaching the fundraising goal.

3)

The graph would be a solid line that represents the situation (180,21)

If it were (200,5) the line would have been dotted and the area shaded would be under the line .

If it were (100,10) the line would have been dotted and the area shaded would be above the line

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
