Question

Loren solved the equation 10 = startfraction 19 over 9 endfraction (149) b for b as part of her work to find the equation of a trend line that passes through the points (1, 130) and (10, 149). what error did loren make? she should have solved 10 = startfraction 9 over 19 endfraction (149) b for b. she should have solved 1 = startfraction 19 over 9 endfraction (130) b for b. she should have solved 149 = startfraction 19 over 9 endfraction (10) b for b. she should have solved 130 = startfraction 9 over 19 endfraction (1) b for b.

Answer 1

The error which Loren made was C. she should have solved 149 = startfraction 19 over 9 endfraction (10) b for b.

What is an Error?

This refers to those miscalculations or misjudgments about a situation or a mathematical solution to give wrong values.

Hence, because Loren is solving an equation of 0 = startfraction 19 over 9 endfraction (149) b for b to find the equation of a trend line that passes through the points (1, 130) and (10, 149), the error she made was option C.

This means that using point (10,149) which takes the form (x,y) the equation will be: 149=19/9(10)+b
