Chapter 4: Q. 624 (page 570)

In the following exercises, use the graph to find the slope and y-intercept of each line. Compare the values to the equation y=mx+b

Short Answer

Expert verified

The equation of the line in the graph is y=4x-1

Step by step solution

01

Step 1. Given Information

The line in the graph

02

Step 2. Find the slope

From the graph, the slope of the graph is

m=RiseRun=41

03

Step 3. Find y-intercept

From the graph, the line cuts the y-axis at y=-1

So, the y-intercept is b=-1

04

Step 4. Substitute the values in the equation

Substitute the values in the equation,

y=mx+by=4x+(-1)y=4x-1
