how to plot a line graph between a set of values against a single value

I have the values of c1 c2 and accuacy . At c1=-5,c2=-7 my model accuracy is 0.81 respectively. The data is given below now my question is how to draw a line graph for this data.

c1 c2 Accuracy

-5 -7 0.81

-7 -4 0.96

-4 3 0.94

-1 6 0.87

5 -3 0.84

3 -1 0.75

9 5 0.82

data = [-5     -7     0.81
    -7    -4      0.96
    -4    3        0.94
    -1    6      0.87
    5    -3     0.84
    3    -1     0.75
    9      5     0.82] ;

c1 = data(:,1) ;
c2 = data(:,2) ;
Acc = data(:,3) ;

c1(end+1) = NaN ;
c2(end+1) = NaN;
c = [Acc ;NaN];

figure
patch(c1,c2,c,'EdgeColor','interp','Marker','o','MarkerFaceColor','flat');
colorbar;
