The dinosaur's ribs and arms are at the intersection of the diagonals shown in the diagram. Compute their equations! First, compute the slopes:

Slope of l:
Slope of m:

I=0.5. And m=-0.75

Step-by-step explanation:

Slope of l:    

0.5

Slope of m:  

✔-0.75

Step-by-step explanation:

Line l:

y - 4 = 0.5(x - 1)

Line m:

y - 5 = -0.75(x - 43)

last part is Line l:

y = 0.5x + 3.5

Line m:

y = -0.75x + 37.25

i think c. but don't trust it.

step-by-step explanation:

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
