-10. One type of system of equations that results in infinite solutions is one where both sides of the equation are exactly equal. Here, setting the second equation equal to -10 becomes 2y - 4x = -10. This can be rearranged into 2y = 4x - 10. Dividing everything by 2 results in y = 2x - 5, which is exactly what the first equation is. Substituting one equation into another, we get 2x - 5 = 2x - 5, which is a true statement for all values of x.
When -10 is placed in the box that would result in a system of equations with infinitely many solutions.
What is system of equation?
"It is a finite system of equations for which we find the common solution."
What is y-intercept?
"It is the point at which the graph of the intersects the Y-axis."
For given equation,
Let 'm' be the solution of 2y - 4x
⇒ 2y - 4x = b
We write above equation in slope-intercept form.
⇒ 2y - 4x = b
⇒ 2y = b + 4x
⇒ 2y = 4x + b
[tex]\Rightarrow y=2x+\frac{b}{2}[/tex]
The y-intercept of above equation is [tex]\frac{b}{2}[/tex].
Also for equation y = 2x – 5 from given system of equations has y-intercept is -5.
We know, the system of an equation has infinitely many solutions when they have the same y-intercept.
[tex]\Rightarrow -5=\frac{b}{2}\\\\\Rightarrow \bold{b=-10}[/tex]
Therefore, when -10 is placed in the box that would result in a system of equations with infinitely many solutions.
