Chapter 4.1, Problem 27E

To determine

To describe:The given equation of line for a given slope and intercept.

Answer to Problem 27E

Values are incorrectly substituted (they are interchanged).

  $\therefore$ Correct equation is $y=2x+7$ .

Explanation of Solution

Given information: Equation is $y=7x+2$ , slope is $2$ , y-intercept is $7$ .

Calculation:

Slope intercept form is $y=mx+b$

m $=2$

  $b=7$

In the given equation, values are incorrectly substituted (they are interchanged).

  $\therefore$ Correct equation is $y=2x+7$ .
