Which statement describes the graph of the system of equations?
qwelly [4]

Answer:

The lines are parallel.

Step-by-step explanation:

The first line is x-y=1

In slope-intercept form, this line has equation: y=x-1

The second line is y-x=1

In slope-intercept form, the line has equation: y=x+1

The slopes of the two lines are the same (m=1)

however, the y-intercepts of these lines are different (-1) and (+1) respectively.

The first choice is correct.

The two lines are parallel and hence will never intersect.

у X -7 -5 -5 -4 -3 -2 ברן 4 LO- To 2 -3 -6 -7 In this graph, the v-intercept of the line is 1. The equation of the line is v=​
GREYUIT [131]

Answer:

The y intercepts is -2

y = 1x-2

Step-by-step explanation:

The y intercept is where it crosses the y axis

The y intercepts is -2

We need to determine the slope, by using to points on the line

(0,-2) and (2,0)

m = (y2-y1)/(x2-x1)

   = (0 --2)/(2-0)

   = (0+2)/(2-0)

   = 2/2

  = 1

The equation for the line is

y = mx+b where m is the slope and b is the y intercept

y = 1x-2
