When janelle woke up it was -3 degrees fahrenheit outside as the morning progressed the temperature rose 2 degrees every hour which line on the graph could represents this scenario

The initial temperature is -3 degrees which makes the y-intercept -3. And the temperature is rising at 2 degrees per hour which means the slope of the line would be 2. We plug this into the equation y=mx+b, m=2, b=-3. So the equation of the line would be y=2x - 3. Hope that helps
