What are your inputs? Which details matter? What have you tried so far?

You can plot some of the features on the graph as follows:
%Define the functions
f1 = @(x) 16*x + 2;
f2 = @(x) -4*x + 8;
f3 = @(x) -14*x + 12 ;
%Plot the functions specifying the type of line and color, and horizontal
%axis limit
fplot(f1, [-0,1], 'k');
hold on;
grid on;
fplot(f2, [-0,1], '--k');
fplot(f3, [-0,1],':k');
%Specify the vertical axis limit
ylim([0,16]);
%Shade the desired area with some color (specified as RGB vector)
x1 = 0:0.01:0.3;
x2 = 0.3:0.01:0.4;
x3 = 0.4:0.01:1;
area(x1,f1(x1),'FaceColor', [0 0.75 0.75]);
area(x2,f2(x2),'FaceColor', [0 0.75 0.75]);
area(x3,f3(x3),'FaceColor', [0 0.75 0.75]);
%plot the points with the desired labels
plot(0,2,'k.', 'MarkerSize', 30);
text(0.01, 2, 'A', 'FontSize', 15);
%
plot(0.3,6.8,'k.', 'MarkerSize', 30);
text(0.31, 6.8, 'B', 'FontSize', 15);
%
plot(0.4,6.4,'k.', 'MarkerSize', 30);
text(0.41, 6.4, 'C', 'FontSize', 15);
%
plot(0.4,6.4,'k.', 'MarkerSize', 30);
text(0.41, 6.4, 'C', 'FontSize', 15);
%
plot(12/14, 0, 'k.', 'MarkerSize', 30);
text(12/14 + 0.01, 0.2, 'D', 'FontSize', 15);
%
plot(0, 0, 'k.', 'MarkerSize', 30);
text(0.01, 0.2, 'E', 'FontSize', 15);
hold off;
This produces the following graph:
