Chapter 4: Q. 650 (page 572)

In the following exercises, find the equation of the line shown in each graph. Write the equation in slope鈥搃ntercept form

Short Answer

Expert verified

The equation isy=2x+1

Step by step solution

01

Step 1. Given information

A graph is given as,

We need to find the equation in slope-intercept form.

02

Step 2. Finding the slope

We know,

m=difference ofy-coordinatesdifference ofx-coordinatesm=y2-y1x2-x1m=3-11-0m=21

03

Step 3. Y-intercept

It is clear from the graph that the y-intercept is(0,1)

04

Step 4. Equation of the line

The equation of a line in slope-intercept form is:

y=mx+cy=2(x)+1y=2x+1
