2/15==x/60
Multiplly
60*2= 120
now divide
120/15= 8
x=8
Write the equation of the line passing through the points (-7,5) and (-5,9):

.
You also have another two points (-3,13) and (-1,17). Look whether coordinates of these points satisfy the line equation:
1. For (-3,13) you have

;
2. For (-1,17) you have

.
Conclusion: All four points lie on the line y-5=2(x+7), so <span>the relationship shown by the data is linear.</span>
