a_2=a_1+d
a_3=a_2+d=a_1+2d
a_4=a_3+d=a_1+3d
...
a_{15}=a_1+14d

Since a_1=-3 and a_{15}=53, the common difference d is

53=-3+14d\implies d=4

Move all terms not containing  x  to the right side of the inequality. You should get x<3

This is what your line should look like. The circle will be open because the is not line under the less than sign. And it will be going toward the left because it is less than greater than is graphed to the right.
