Chapter 8, Problem 2CR

To determine

To write:

A linear equation in slope-intercept form. Identify the slope and y-intercept.

Answer to Problem 2CR

The equation $y=2x+1$ is in slope-intercept form with a slope of 2 and y-intercept is1.

Explanation of Solution

Calculation:

We know that slope-intercept form of equation is in format: $y=mx+b,\text{where,}$

  $\begin{array}{l}m=\text{Slope of line,}\\ b=\text{The }y\text{-intercept}\end{array}$

The equation $y=2x+1$ is in slope-intercept form.

Upon comparing our equation with standard slope-intercept form, we can see that thevalue of m is 2 and the value of b is 1. Therefore, the slope of our equation is 2 and y-intercept is1.
