Please check the explanatio.
Step-by-step explanation:
Solving Part b)
We know that the slope-intercept form of the equation line is
where m is the slope and b is the y-intercept
Given the equation
Re-writing the equation in the slope-intercept form
Here, m=-2 and b=8
Thus, the equation in the slope-intercept form will be:
Solving Part c)
As you sold two pounds of cheddar cheese.
i.e. y=2
substituting y=2 in the slope-intercept form of the line equation
Subtract 8 from both sides
Divide both sides by -2
You sold 3 pounds of swiss cheese.
Solving Part d)
putting x=2.5 in the equation
The sides are not equal
<em>FALSE</em>
Thus, x=2.5 does not make any sense in the context of the problem.
