Given the following system of equations and their graph below, what can be determined about the slopes and y-intercepts of the system of equations?


(Graph)
4x + 2y = −2
x − 3y = 24

The slopes are different, and the y-intercepts are different.

Respuesta :

Answer:

  The slopes are different, and the y-intercepts are different

Step-by-step explanation:

The lines on the graph are not parallel, so the slopes are different.

The lines on the graph intersect the y-axis in different places, so the y-intercepts are different.

Answer:

The slopes are different, and the y-intercepts are different.

Step-by-step explanation:

From the graph:

Parallel lines have the same slope.

The lines are not parallel, therefore have the different slopes.

y-intercepts are different (look at the picture)

-1 and -8.

Answer:

The slopes are different, and the y-intercepts are different.

From the system of equations:

The slope-ntercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the equations of a lines in the standard form (Ax + By = C).

Convert ot the slope-intercept form:

[tex]4x+2y=-2[/tex]         subtract 4x from both sides

[tex]2y=-4x-2[/tex]           divide both sides by 2

[tex]y=-2x-1[/tex]

Therefore we have the slope m = -2, and the y-intercept b = -1.

[tex]x-3y=24[/tex]             subtract x from both sides

[tex]-3y=-x+24[/tex]         divide both sides by (-3)

[tex]y=\dfrac{1}{3}x-8[/tex]

Therefore we have the slope m = 1/3, and the y-intercept b = -8.

-2 ≠ 1/3 and -1 ≠ -8

The slopes are different, and the y-intercepts are different.
