Expert Solution

Answer to Problem 75E

The function is y=7x643 .

Explanation of Solution

Given information : The given coordinates are (2,1) and (4,6) .

Concept used : we must find out the slope of the equation. We can do this by the slope formula for the slope, m , is found by taking the change in y and a dividing it by the change of x .

Graph :

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 2.2, Problem 75E

Calculation :

  m=y2y1x2x1=614+2=76

So,

  yy1=m(xx1)y1=76(x+2)y1=7x673y=7x6+173y=7x6+373y=7x643
