The coefficient for Lunchstandard, 0.69, is the difference in the intercept between the students who qualified for free/reduced lunch and those who did not (standard). To get the intercept for students who did not qualify for free/reduced lunch, add Lunchstandard to Intercept. Then combine with the slope to get the equation for the standard lunch line.

a) Write out the two regression lines, one for each lunch status [round parameter estimates to two decimal places]. No other interpretations needed.
