The blue dot is at what value on the number line?

I think it’s 4 if the lines are going up by 2

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.

Number nine is f(x)= 40x : ) hoped i ya
