(2,-3) and (-2,5)

Step-by-step explanation:

Let us graph the two equations one by one.

1.

If we compare this equation with the slope intercept form of a line which is given as

we see that m = -1 and c =1

Hence the slope of the line is -2 and the y intercept is 1. Hence one point through which it is passing is (0,1) .

Let us find another point by putting x = 1 and solving it for y

Let us find another point by putting x = 2 and solving it for y

Hence the another point will be (2,-3)

Let us find another point by putting x = -2 and solving it for y

Hence the another point will be (-2,5)

Now we have two points (0,1) ,(1,-1) ,  (2,-3) and (-2,5) we joint them on line to obtain our line  

2.

It represents the parabola opening upward with vertices (1,-4)

Let us mark few coordinates so that we may graph the parabola.

i) x=0 ; ; (0,-3)

ii)x=-1 ; ; (-1,0)

iii) x=2 ; ;(2,-3)

iii) x=1 ;  ;(1,-4)

iii) x=-2 ;  ;(-2,5)

Now we plot them on coordinate axis and line them to form our parabola

When we plot them we see that we have two coordinates (2,-3) and (-2,5) are common , on which our graphs are intersecting. These coordinates are solution to the two graphs.
