The value fo k is $\frac{13}{2}$ . This is because c, the constant, is the y-intercept. The graph shows where the line intersects the y-axis, which is -3. So you substitute -3 with c. To find the value of k, plug in the coordinate with the x and y values and then solve for k.

Let g be the number of grandchildren, and d be the number of dogs. They both have only one head, so the number of heads is

$g+d=33$

Grandchildren have 2 legs, while dogs have 4. So, the total number of legs is

$2g+4d=84$

From the first equation (the one for the heads) we can derive

$g=33-d$

Substitute this into the second to get

$2g+4d=84 \implies 2(33-d)+4d=84 \iff 2d=18 \iff d=9$

So, there are 9 dogs and (from the first equation

$g=33-9=24$
