<span>Helena is correct in saying that the point-slope form
will generate the equation. The point-slope form is written as:</span>
<span>
</span>
y-y₁ = m(x-x₁), where,
m = (y₂-y₁)/(x₂-x₁) is the slope of the line
(x₁,y₁) and (x₂,y₂) are the coordinates of the two points
On the other hand, the slope-intercept form is written as:
y = mx + b, where,
m is the slope of the line
b is the y-intercept
In this case, since only two points were given, the y-intercept of the line is not readily known. Thus, it is only through the point-slope form that the equation of the line can be determined. This is because it only requires the substitution of the x and y-coordinates of the points in the equation.
We can find out two point on the line (0,2)and(4,1)
The slope =(2-1)/(0-4)=-1/4
Answer:
Step-by-step explanation:
Sinse in this case you are dealing with direct variation, all you are doing is taking the <em>multiplicative</em><em> </em><em>inverse</em><em> </em>of 4, which is ¼:
This option is not an answer choise. Perhaps there was a typographical errour.
