Putting the equations in slope-intercept form changes the system from

15x + 9y = 36

10x + 6y = 36


To


y = −5
3
x + 4

y = −5
3
x + 6

Which statements describe the system of equations? Check all that apply.
The lines are parallel.
The lines coincide.
The y-intercepts are equal.
The slopes are equal.
The system has one solution.

Respuesta :

[tex]15x+9y=36 \rightarrow y=-\frac{5}{3}x+4 \\ \\ 10x + 6y = 36 \rightarrow y=-\frac{5}{3}x+6[/tex]

The lines are parallel.

The slopes are equal.

Explanation:

The standard form of the equation of a line is given by the form:

[tex]Ax+By=C \\ \\ \\ Where: \\ \\ A \ is \ a \ positive \ integer \\ \\ B,C \ are \ integers[/tex]

On the other hand, the slope-intercept form of the equation of a line is given by the form:

[tex]y=mx+b \\ \\ \\ m:Slope \\ \\ b:y-intercept[/tex]

So let's convert each equation from the standard form to the slope-intercept form:

So, for the first equation:

[tex]15x+9y=36 \\ \\ Solving \ for \ y: \\ \\ 9y=-15x+36 \\ \\ y=\frac{-15x+36}{9} \\ \\ y=-\frac{5}{3}x+4[/tex]

So, for the second equation:

[tex]10x + 6y = 36  \\ \\ Solving \ for \ y: \\ \\ 6y=-10x+36 \\ \\ y=\frac{-10x+36}{6} \\ \\ y=-\frac{5}{3}x+6[/tex]

As you can see both equations have the same slope but different y-intercepts meaning that they are parallel. So these are the correct options:

The lines are parallel.

The slopes are equal.
