Which graph correctly solves the system of equations below? x2 + y2 = 25 y = x + 1

We have
x2 + y2 = 25
y = x + 1

using a graph tool
see the attached figure

the solution  are the points (3,4) and (-4,-3)

The first thing you should realize is what kind of functions you have:
 x2 + y2 = 25 
 It is a circle of radius r = 5 units.
 y = x + 1
 It is a line of positive slope.
 The solution is the cut points of both graphs.
 Attached graphic and analytical solution.

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
