1) You need to graph this one in order to find out the ordered pair. Your y-intercept is positive 4, so that's where you should start. From there, your slope is negative 11 so you'll go down 11 times and move one over. The line should go across the ordered pair of (1, -7). So, your answer is C (1, -7).

2) c = 65h
In this equation, c represents the total cost. 65 is the price charged per hour to fix a leak. So, if I were to say it took a plumber two hours to fix a leak then my equation would be:

c = 65(2)
c = 130

Thus, the cost is $130.

3) The problem says solve for x, however, I don't see the input of x anywhere.

4) c = b - bx

c = b(1-x)

c/b = 1 - x

c/b - 1 = -x

-c/b + 1 = x

This equation is read as: negative c over b plus 1 equals x

(y^2-7y-5)-(-3y^2+3y-4)
=y^2-7y-5+3y^2-3y+4
=3y^2+y^2-7y-3y-5+4
=4y^2-10y-1

In short, the answer would be 4y^2-10y-1 (Option D).

Hope this helps !
