Question 972818: Mrs. Bailey gives a test, and her students� scores range from 30 to 70. She decides to curve the scores, so that they range from 65 to 95. Let �x� be an original score, and �y� be a curved score. Using the ordered pairs (30,65) and (70,95), write the equation in slope/intercept form that she should use to curve the test scores.
what will the original score of 62 become?
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
slope of the line between the ordered pairs is (95-65)/(70-30) = (30/40)=3/4
point slope formula
y-65=(3/4)(x-30)
y-65=(3/4)x - 22.5
y=(3/4)x + 42.5
if x=62
y=46.5 +42.5=89
It is a high score curved, but the student was at the upper end of the original interval.
