Chapter SH, Problem 3.9EP

To determine

To graph the equation $y=4$ .

Answer to Problem 3.9EP

Graph:

  

Explanation of Solution

Given information:

The equation is $y=4$ .

Calculation:

  $y=4$

Rewrite above equation in the slope intercept form

  $y=0x+4$

The general slope-intercept form of a linear equation is

  $y=mx+b,\mathrm{.......}(2)$

where m is the slope and b is the y intercept.

On comparing equation (1) and (2),

  $m=0$

And Y-intercept, $b=4$

The grapg of $y=4$is given below:

  

Slope: The steepness of a line expressed as a ratio, using any two points on the line.

Y-intercept: The value of y at the point where a line crosses the y-axis.
