Try this
x = 103.3;
y = 31.1;
angle_yAxis = 139;
angle_xAxis = 90 + (180-139);
slope = tand(angle_xAxis);
x_range = 102:0.01:106;
y_range = slope*(x_range - x) + y;
figure;
plot(x, y, '+', 'LineWidth', 2, 'MarkerSize', 8);
hold on
plot(x_range, y_range);
xlim([102 106]);
ylim([30 33]);
vectors x_range and y_range contain the points lying on the line.

You can change the line to
dist = distance(x, y, x_range.', y_range.');
