 Question 106945: A credit manager rates each applicant for a car loan on a scale of 1-5 and then deterines the interest rate. Find the equation of a line in slope-intercept form that goes thru these points. Credit Rating Interest Rate 1 24 2 20 3 16 4 12 5 8Answer by cheesey(22)   (Show Source): You can put this solution on YOUR website!first select two points to find the slope of the line. I chose (2, 20) (1, 24). Then the slope is (20-24)/(2-1) = -4 Using point-slope form: y - y* = m(x - x*), where y*, x* are one point given. Thus y - 20 = -4(x - 2) y - 20 = -4x + 8 y = -4x + 28 is one such equation of this line in y=mx + b form. Chose a different point and your "b" will change.
