Find an explicit formula for the arithmetic sequence − 45 , − 30 , − 15 , 0 , . . −45,−30,−15,, 45, comma, minus, 30, comma, minus, 15, comma, 0, comma, point, point, point.

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
