Responses

y=−2x+1
y equals negative 2 x plus 1

y=x+1
y equals x plus 1

y=12x+1
y equals Start Fraction 1 over 2 End Fraction x plus 1

y=x+2

Answer 1

A family is going from Dallas, Texas, to Los Angeles, California. They have traveled 500 miles so far. The next day, their average speed is 70 miles per hour. Write an equation for the distance they traveled, y , and the hours they have driven, x . Indicate whether this is a proportional or a nonproportional situation.(1 point) Responses y=70x+500, nonproportional y equals 70 x plus 500 , nonproportional y=70x, proportional y equals 70 x , proportional y=500x+70, nonproportional y equals 500 x plus 70 , nonproportional y=70x+500, proportional
