Y=(1/2)x^2 + 2x - 1
3x - y = 1, or y=3x-1
substitute
3x-1=(1/2)x^2+2x-1
0=(1/2)x^2-x
0=x(0.5x-1)
x=0,2
y=2+4-1=5
3(2)-1=5.
When x=2 y=5 (2,5) is one solution
when x=0, y=-1, (0,-1) is the other solution

Answer:</h2>
<u>The distance is</u><u> 0.66 units</u>
<h2>
Step-by-step explanation:</h2>
The formula for distance is
S = y2-y1 / x2-x1
S= 4-6 / 2-5
S = -2/-3
S = 0.66
